[Bug fortran/34788] New: Error diagnostic issued passing array element to explicit shape dummy argument
Gfortran version 4.3.0 20080114 (experimental) [trunk revision 131520] issues a diagnostic call b(z(1)) 1 Error: Element of assumed-shaped array passed to dummy argument 'x' at (1) on the attached program. This diagnostic is (a) misleading - b is NOT an assumed-shape array, and (b) incorrect.

--- Comment #1 from dgregor at gcc dot gnu dot org 2008-01-15 05:38 --- This is not a bug. In the line that prints "L-value ref" where the reporter expected "R-value ref", the call to the lvalue reference constructor that we're seeing comes from inside the body of the source() function, which is returning a reference to a static variable. Since the variable is static, it is treated as an lvalue, and therefore we do a construction with S's lvalue constructor (which prints out "L-value ref"). Then, we don't actually need to perform another construction to build "u" (since we constructed the result of the call to source() in place), so there is no "R-value ref" at the end of the output/ -- dgregor at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34700

[Bug c++/34399] [4.3 regression] ICE on invalid friend declaration of variadic template
--- Comment #4 from dgregor at gcc dot gnu dot org 2008-01-15 00:43 ---
So, this is another case where we have a bug in our handling of C++98 that just
happens to have been reported against variadic templates. The error in the code
example is that 'N' in the friend declaration needs to be a parameter pack,
e.g.,
template friend void A::A::foo();
That way, we're exactly matching the signature of the template A. The problem,
in the compiler, is that without this exact match we don't get to the primary
template's definition, and when we can't find A::A we end up with a
TYPENAME_TYPE... not the kind of thing we want at this point.
In C++98, we can create the same issue by using non-type template parameters
that don't match types exactly, e.g.,
template struct X
{
void foo();
};
struct Y {
template friend void X::X::foo();
};
That causes the same kind of ICE.
I'm looking into this issue now...

Jerry, do you have an idea?
Confirm. Reduced test case:
character a(6)
a = transfer("abcdef", a,size(a))
write(*,'(T20,A3, T1,A4, T5,A2, T7,A2, T9,A4, T17,A1)') a
end
Expected:
b c d efa
Actual:
b c d ef
Using "character(5)" works.
(Don't forget to test also the big test case; ifort for instance passes the
test above, but writes non-printable characters (combined with "a" and " ") for
column > 135 while g95, openg95/sunf95 and NAG f95 work.)

[Bug c++/27177] [4.1/4.2/4.3 Regression] ICE in build_simple_base_path, at cp/class.c:474
--- Comment #17 from crowl at google dot com 2008-01-14 21:29 ---
Subject: Re: [4.1/4.2/4.3 Regression] ICE in build_simple_base_path, at
cp/class.c:474
The consensus of the C++ standards reflector is that all three
following code snippets are well-formed.
explicit:
struct B {};
struct D : public B {
static const int i = sizeof((B*)(D*)0);
};
implicit:
struct Z {};
struct A : Z {};
Z* implicitToZ (Z*);
struct B : A {
static const int i = sizeof(implicitToZ((B*)0));
};
non-null:
struct B {};
struct D;
D* p;
struct D: public B {
static const int i = sizeof ((B*)p);
};
The rational is that even though the classes are not complete
within their body, the bases must be known. The reason is that
other features of the language, like co-variant returns, would fail.
Since the bases are known, the conversions are well-formed.

[Bug c++/33887] [4.1/4.2/4.3 Regression] Reference to bitfield gets wrong value when optimizing
--- Comment #22 from aoliva at gcc dot gnu dot org 2008-01-14 19:56 --- Both are cases in which the absence of bit-field reduction *on widening conversions* causes the problem. I realize the absence of such reductions can be harmful in other cases as well, e.g. division and right-shifts. But for most cases, modulo semantics guarantees the correct results as long as we stick to the narrower type. However, when modulo semantics is required, reduction must take place, e.g. for compare operations that don't disregard the bits that are not in the type's implied mask. I believe the module semantics is the reasoning behind the no-reduction policy. But I do see that we fail to implement it properly, and I don't know whether it is the front-end's responsibility to provide the missing bits explicitly, or the middle end to cover for what the front end might be assuming the middle end will provide. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33887

It seems silly for a project to get warnings in the below case. It seems silly
to require that one specialize just to avoid the warning.

template
void foo(T t) {

void bee() {

--- Comment #20 from rguenth at gcc dot gnu dot org 2008-01-14 16:55 --- So even if you fix that, and you'll end up with D.2029; : D.2029 = () (unsigned int) ((int) x.i + -1); x.i = D.2029; if (D.2029 != 16777215) goto ; else goto ; before expand, the truncation at the store to register D.2029 still is not reflected in code generated by expand, if the language does not have REDUCE_BIT_FIELD_OPERATIONS set. Which means that the GIMPLE IL bool retval.0; D.2025; int D.2026; int D.2027; unsigned int D.2028; D.2029; unsigned int D.2030; unsigned int D.2031; D.2025 = x.i; D.2026 = (int) D.2025; D.2027 = D.2026 + -1; D.2028 = (unsigned int) D.2027; D.2029 = () D.2028; x.i = D.2029; D.2025 = x.i; retval.0 = D.2025 != 16777215; if (retval.0) still does not have frontend independent semantics.

I'm no language lawyer, but the whole exercise is supposed to be valid. It has been mutilated for msvc2k5, and it works there. It also works with g++ when it doesn't fault (that is when i use an alternative implementation). Icc 10.1 doesn't complain either before crashing ;) So, to me, with my rosy teinted glasses strapped on, it has never been an ice-on-invalid. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34774

Reduced testcase:
template
struct shift {
enum {
n0 = (unsigned)shifts,
n = n0 ? 0 : n0,
n_comp = -n
} x;
};
it looks like we substitute n into -n but do not stop substituting once
we hit a dependent expression (n0).

--- Comment #9 from rguenth at gcc dot gnu dot org 2008-01-14 12:35 --- The testcase in comment #3 looks valid(?), at least EDG accepts it. The problem is we try to fold_non_dependent_expr n = n0 > max_shift ? max_shift : n0, but substituting n0 makes this expression dependent and we leak template param lists to fold. -- rguenth at gcc dot gnu dot org changed: What|Removed |Added Keywords|ice-on-invalid-code |ice-on-valid-code Priority|P4 |P2 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34774

[Bug target/33281] gfortran crt2.o not found under Vista
--- Comment #11 from keithmarshall at users dot sourceforge dot net 2008-01-14 12:15 --- (In reply to comment #9) > Fix committed to mainline. > As a MinGW administrator, I am dismayed that you consider this __USE_MINGW_ACCESS kludge as a solution to this bug; I would like this particularly nasty kludge to go away, from the MinGW code base, as soon as is practicably possible. My own view on this is, that since X_OK has no meaning on any platform supported by MinGW, our headers simply should not define it. Danny Smith has advised me that I cannot do that, since GCC needs it, if I don't define it, GCC will give an arbitrary value of one, which will simply reintroduce the old broken behaviour; IMO, that is wrong: if I don't define it, then it is because it should not be used, and GCC should respect that. Danny has further advised me that, if I were to adopt the next best compromise, and define X_OK with a value of zero, that that too would break GCC, because it uses X_OK in other contexts than the mode argument to access(), and in those contexts the value of zero would not work. If this is indeed the case, then I would respectfully suggest that such usage is a violation of IEEE-1003.1, which explicitly defines F_OK, R_OK, W_OK and X_OK for use as values for composing the mode argument to access(), (and for no other purpose).

uClibc developers pointed me here saying this is a known bug for the gcc-4.x
line, I was able to reproduce this bug on gcc-4.1.2 also.
