[Bug c++/58147] New: Template template parameter
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58147
Bug ID: 58147
Summary: Template template parameter
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: potswa at mac dot com
Although the usage is a bit dubious, name lookup of the identifier after a
nested-name-specifier should not find a template parameter name. But it does,
seemingly only for a template template parameter.
template typename struct b {};
template template typename class b struct d
: b int
{ using d::b int ::b; };
template struct d b ;

[Bug middle-end/52544] compilation fails with -finstrument-functions and sse c code
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52544 --- Comment #6 from Rodrigo Campos rodrigo at sdfg dot com.ar --- Actually, I recently find out that the memory corruption thing was not a GCC bug. It was a really weird error that only appears in the library if you do a print to stdout (not stderr) before some thing happens. And when I added a print compiling without -finstrument-functions, I did not added at the **very** beginning (but after some other thing, if not you will not hit the bug) and when compiling with -finstrument-functions it was added there. So I did not hit this weird bug when I tried to :) So I'm just hitting the bug originally reported with the same symptoms, sorry for the noise! If I can help in any way, please let me know :-) Thanks a lot, Rodrigo

[Bug fortran/44978] derived types are resolved more than once
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44978
--- Comment #17 from Dominique d'Humieres dominiq at lps dot ens.fr ---
In what follows Janus' patch will refer to
http://gcc.gnu.org/bugzilla/attachment.cgi?id=30629
and Mikael's patch to
http://gcc.gnu.org/bugzilla/attachment.cgi?id=30633
Although there are still duplicate errors, both patches regtest cleanly and are
a significant improvement. I have seen the following differences between the
two patches (I'll attach the full differences):
(1) pr43591, Mikael's patch output the additional error
pr43591.f90:8.77:
procedure(number_flavor_states), nopass, pointer :: number_flavor_states
= NULL()
1
Error: Interface 'number_flavor_states' at (1) must be explicit
For both patches the error
pr43591.f90:15.23:
integer, dimension(physical%number_particles_out(),
1
Error: Expression at (1) must be of INTEGER type, found UNKNOWN
is printed twice.
(2) pr48095, the error
pr48095.f90:7.79:
procedure(get_area), pointer, pass(this) :: get_special_area = get_my_area
1
Error: Interface mismatch in procedure pointer assignment at (1): Type mismatch
in argument 'this' (CLASS(rectangle)/TYPE(rectangle))
is printed three times with Janus' patch and only twice with Mikael's one.
(3) pr55983, with Janus' patch, the last error is
pr55983.f90:16.32:
class(bcd_t), pointer :: bcx, bcy
1
Error: The pointer component 'bcx' of '__class_solver_mpdata_m_Mpdata_t' at (1)
is a type that has not been declared
while with Mikael's patch it is
pr55983.f90:16.37:
class(bcd_t), pointer :: bcx, bcy
1
Error: The pointer component 'bcy' of 'mpdata_t' at (1) is a type that has not
been declared
For a clean tree it is
class(bcd_t), pointer :: bcx, bcy
1
Error: The pointer component 'bcx' of 'mpdata_t' at (1) is a type that has not
been declared
(4) pr58023, compiling both tests with Janus' patch gives an ICE, while with
Mikale's patch the first test gives a second error
pr58023.f90:11.34:
procedure(mr), pointer :: mr2
1
Error: Procedure pointer component 'mr2' with PASS at (1) must have at least
one argument
I also took the opportunity to extend your pr51945 change (hunk below)
to the whole loop.
This also fixes pr58023#c0. pr58023#c1 is fixed if I replace the following

[Bug libstdc++/58148] New: [C++11] Fails to insert iterator range into sequence container with -D_GLIBCXX_DEBUG when conversion is needed
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58148
Bug ID: 58148
Summary: [C++11] Fails to insert iterator range into sequence
container with -D_GLIBCXX_DEBUG when conversion is
needed
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++

Reporter: ai.azuma at gmail dot com
Created attachment 30644
-- http://gcc.gnu.org/bugzilla/attachment.cgi?id=30644action=edit
reproducing source code and output of -v option
The following valid code fails to compile with 4.9.0 20130804 and
`-D_GLIBCXX_DEBUG':
//
#include vector
int main()
{
std::vectorwchar_t v;
char c = 'a';
v.insert(v.begin(), c, c); // compile error
}
//
The above code successfully compiles with 4.9.0 20130728 and
`-D_GLIBCXX_DEBUG'. So this seems a regression, which has been introduced
between 20130728 and 20130804.
The same problem also occurs for `std::deque'.

See read_module, the code that comes after the comment: /* See if the symbol has already been loaded by a previous module. If so, we reference the existing symbol and prevent it from being loaded again. This should not happen if the symbol being read is an index for an assumed shape dummy array (ns != 1). */ - Normally, mio_component (called from mio_component_list, from mio_symbol) associates a component pointer to the corresponding pointer id so that it can be referenced in expressions for example. As the type is not loaded from file (see above) the association isn't done either. - get_neighbors contains an expression (in the result's array spec) referencing max_degree, one of matrix::sparse_matrix's components. Because of the above, the reference is not associated with the corresponding component pointer, and it leads to the internal error.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44978 --- Comment #20 from Dominique d'Humieres dominiq at lps dot ens.fr --- I have run my tests with the patch in comment #17. As expected it fixes pr58023#c1, but it also remove the duplicate error in pr43591.f90 and pr43591.f90:15.55: integer, dimension(physical%number_particles_out(), 1 Error: Expression at (1) must be of INTEGER type, found UNKNOWN I am a little bit puzzled by this error. I think it is an attempt to emit if for physical%number_flavor_states(), but the error does not give the right locus (probably due to the continuation line). I don't understand why it is removed by the change and don't know how bad it is to remove it. My analysis for pr48095 has been to fast: there is no duplicate, but two different errors: pr48095.f90:7.79: procedure(get_area), pointer, pass(this) :: get_special_area = get_my_area 1 Error: Interface mismatch in procedure pointer assignment at (1): Type mismatch in argument 'this' (CLASS(rectangle)/TYPE(rectangle)) pr48095.f90:7.79: procedure(get_area), pointer, pass(this) :: get_special_area = get_my_area 1 Error: Interface mismatch for procedure-pointer component 'get_special_area' in structure constructor at (1): Type mismatch in argument 'this' (CLASS(rectangle)/TYPE(rectangle)) The locus for the second error should probably at the end of get_special_area. With the Mikael's patch + the change in comment #17, I have spotted two remaining duplicates: the test in comment #4 and gfortran.dg/spec_expr_6.f90. Indeed I have probably overlooked other cases (I have no idea on how to do an exhaustive search).

[Bug debug/58150] New: debug info about definition of enum class not emitted if the declaration was already used in a template
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58150 Bug ID: 58150 Summary: debug info about definition of enum class not emitted if the declaration was already used in a template Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: debug Assignee: unassigned at gcc dot gnu.org Reporter: b.r.longbons at gmail dot com Created attachment 30649 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=30649action=edit minimal testcase If an enum class has a forward declaration and it is used as a class member (functions seem to be okay), the full debuginfo is not emitted when the definition appear later in the TU. This makes debugging practically impossible. enums are unusual in that they can be fully used even when they have just a definition. Tested gcc versions: g++-4.6 (Debian 4.6.4-2) 4.6.4 g++-4.7 (Debian 4.7.3-4) 4.7.3 g++-4.8 (Debian 4.8.1-8) 4.8.1 Versions before 4.6 did not implement forward declarations of enum classes, so this bug is primordial. The relevant part of the debug information looks like: 134: Abbrev Number: 3 (DW_TAG_enumeration_type) 35 DW_AT_name: (indirect string, offset: 0x84): ByteCode 39 DW_AT_enum_class : 1 39 DW_AT_declaration : 1 39 DW_AT_byte_size : 1 3a DW_AT_decl_file : 1 3b DW_AT_decl_line : 3 Whereas clang generates: 16f: Abbrev Number: 6 (DW_TAG_enumeration_type) 70 DW_AT_type: 0x64 74 DW_AT_enum_class : 1 75 DW_AT_name: (indirect string, offset: 0x98): ByteCode 79 DW_AT_byte_size : 1 7a DW_AT_decl_file : 1 7b DW_AT_decl_line : 10

[Bug c/50584] No warning for passing small array to C99 static array declarator
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50584 Malcolm Inglis me at minglis dot id.au changed: What|Removed |Added CC||me at minglis dot id.au --- Comment #2 from Malcolm Inglis me at minglis dot id.au --- GCC 4.8.1 is still failing to warn for static array indices in function parameters. The C99 status pages say this feature has been done since 3.1: http://gcc.gnu.org/gcc-3.1/c99status.html Was there a regression?
