[Bug fortran/32937] segfault with string and -fdefault-integer-8
--- Comment #4 from fxcoudert at gcc dot gnu dot org 2007-08-10 15:31 --- The problem with integer kind is from the string length: character(2_8) :: c(2) integer :: i c = aa print *, c .eq. aa call foo ((/(c(i), i = 1,2)/)) print *, c .eq. aa contains subroutine foo (c) character(*), dimension(:) :: c end subroutine foo end If you compile it and set a breakpoint on the translation of the string comparison (which is trans-expr.c:1172), and print out the tree that is the length of c (lse.string_length), you get the first time: integer_cst 0x2b81534a6930 type integer_type 0x2b81531d45b0 int4 constant invariant 2 $3 = void which is correct, while the second time you get: integer_cst 0x2b81534a61b0 type integer_type 0x2b81531d4750 int8 constant invariant 2 which is wrong: the charlen type is int4, not int8. Somehow, the conjunction of function call and temporary produces this, because if you remove either the function call or the need for a temporary, the code is then correct. From what I seem there is a cl-backend_decl somewhere (or a string_length) that is generated refering to this int8 constant, which should never happen. I haven't been able to find out where this happens, though. PS: in the mean time, I've found what I think is an unrelated bug. This is the only occurrence that I could find of an cl-backend_decl with wrong type, but it doesn't fix this bug ;-) Index: trans-expr.c === --- trans-expr.c(revision 127334) +++ trans-expr.c(working copy) @@ -1855,6 +1851,7 @@ gfc_conv_aliased_arg (gfc_se * parmse, g gfc_array_index_type); tmp = fold_build2 (MINUS_EXPR, gfc_array_index_type, tmp, tmp_se.expr); + tmp = fold_convert (gfc_charlen_type_node, tmp); expr-ts.cl-backend_decl = tmp; break; -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32937
[Bug debug/33044] New: Local variables in C++ constructor not visible for debugging
SUMMARY:
In gcc 3.2.3 (and other versions) the DWARF information created by gcc does not
create DW_AT_location attribute for local (static) variables inside a C++
constructor.
WHAT::
The reproducer below shows TWO problems related to debug information available
regarding variables inside a C++ a constructor. One type is (1) a local
variable inside a constructor and second type is (2) a local _static_ variable
inside a constructor. Sometimes TV is able to see the case (1) but only in the
Program Browser (PB); but case (2) is never correctly shown in TV, neither when
Diving, Stack Frame or in PB.
For some versions of gcc TV can show type (1) in the PB, but for all gcc
versions TV fails to show type (2) at all.
This problem is not related to TV alone, GDB fails to see these variables as
well.
On gcc 3.2.3, TV can see type (1) only in PB, but type (2) is
not visible to TV at all (only in symtable).
With PGI-7.0.5 (and some other non-gcc compilers) TV can see everything
alright.
REPRODUCE/TEST::
See attached c++ file.
dbreak 25
drun
dprint iii
dprint foofoo
WHY::
In some gcc versions there is no DWARF information whatsoever related to types
(1) and (2).
In gcc 3.2.3 (and others, e.g. 4.0.3) the DWARF information created by gcc does
not create DW_AT_location attribute for neither type (1) and (2), e.g.
less tx_local.gcc3.2.3.txt
21760: Abbrev Number: 41 (DW_TAG_variable)
DW_AT_name: foofoo
DW_AT_decl_file : 1
DW_AT_decl_line : 28
DW_AT_type: 178a
less tx_local.pgi7.0.5.txt
11048: Abbrev Number: 14 (DW_TAG_variable)
DW_AT_name: foofoo
DW_AT_type: 1864
DW_AT_location: 5 byte block: 3 30 e0 4 8 (DW_OP_addr: 804e030; )
Therefore TV (or gdb) does not have enough information to resolve these
variables.
These variables do exist in the symtable, e.g.:
d1. sgrep foofoo
{kind loader_symbol} {id 1|795} {full_pathname
##/nfs/netapp0/user/home/seppo/tx_local.out_gcc3.2.3#tx_local_var_cpp_constructor.cxx/_ZZN1AC1Eii\

{
int iii;
iii = 42;
c_ = a_ * b_;
c_ += iii;
static const int foofoo[6][4] = { {0,1,2,3},
{1,2,3,4},
{2,3,4,5},
{3,4,5,6},

printf(foofoo = %d\n, foofoo);
}

[Bug c++/33041] New: g++ incorrectly resolves an identically named templated struct in a super class
The following code compiles, but produces an incorrect result. I think this is
because g++ seems to incorrectly determine which templated struct foo should be
used (the one at the namespace level versus the member struct in bar). The two
lines in main() should produce the same result I think, but do not in practice.
The code should, when executed, produce 2\n2\n I think, but it produces
1\n2\n, showing an incorrect resolving of foodouble in the first line of
main().
Reproducable using 3.3 and 4.0 on OS X as well.
Test case code:
#include iostream
struct bar {
typedef bar type;
template typename A
struct foo {
static const int value = 2;
};
};
template typename B
struct foo : bar {
static const int value = 1;
};
int main() {
// fooint is the foo struct at namespace level, foodouble should be
the foo struct within bar, but it is not in g++
std::cout fooint::foodouble::value std::endl;
// fooint is again the foo struct at namespace level, ::type
explicitly takes its superclass so foodouble is the foo struct within bar.
std::cout fooint::type::foodouble::value std::endl;
}

--- Comment #5 from kargl at gcc dot gnu dot org 2007-08-10 20:47 --- (In reply to comment #4) (In reply to comment #3) UGH. I'd rather document gfortran's behavior than add additional hacks into the compiler. Hum, I was of the same opinion at first. What somehow convinced me that it might be worth the price is that the use of DATE_AND_TIME to initialize the random seed is actually in the Metcalf book. There is a nice chance that it will end up in most user codes. Ugh**2 :-) I loaned my copy of MR to colleague and it never returned. I can't imagine that MR did not add some qualifier to quality of seeds that one gets from DATE_AND_TIME. Your attempt to randomize the seeds really isn't all that good because there is such a limited amount of entropy in year, month, day, and hour. I have analyzed your algorthim closely enough, so what is the effect on someone who actually knows how to properly seed gfortran's PRNG. Are there any degenerate side effects? The person of c.l.f is simply doing a rather crappy test of randomness. See my replies. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32812

[Bug libfortran/32812] random_seed and date_and_time
--- Comment #6 from fxcoudert at gcc dot gnu dot org 2007-08-10 21:28 --- (In reply to comment #5) Your attempt to randomize the seeds really isn't all that good because there is such a limited amount of entropy in year, month, day, and hour. I do agree. There's no way I'm adding entropy just by a bijective function :) I have analyzed your algorthim closely enough, so what is the effect on someone who actually knows how to properly seed gfortran's PRNG. Are there any degenerate side effects? There shouldn't be any side effect. What I'm doing is that I'm shuffling the bytes between user-provided and internal KISS seed so that the first bytes of the user seed end up distributed in both parts of the KISS seed (used for MSB and LSB of the final random numbers); same thing for the last bytes. In that way, whether the user seed has stronger first or last elements, it will not reflect on the quality of the MSB/LSB generated. So, since it's just shuffling bytes (and it's a bijective operation, of course), I don't think I'm messing with any of the properties of the generator. -- fxcoudert at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |fxcoudert at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Last reconfirmed|2007-07-28 13:07:22 |2007-08-10 21:28:07 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32812

[Bug c++/33045] New: [c++0x] Incorrect decltype result for function calls.
Given: int f (); template typename struct incomplete; incompletedecltype(f()) i; GCC says (when invoked with -std=c++0x): 'incompleteint i' has incomplete type However, the latest standard draft (n2369) states in section 7.1.6.2 paragraph 4: if e is a function call [...], decltype(e) is the return type of that function. So the error should've been: 'incompleteint i' has incomplete type. -- Summary: [c++0x] Incorrect decltype result for function calls.
