This works for me with 4.0.4, 4.1.2, 4.2.0, and 4.3.0 even with GC settings so
it always runs.

I'm trying to compile CP2K with gfortran (yesterday's mainline), but I'm
experiencing ICEs. Since it seems to be happening more often with CP2K I've
added this metabug.
the first one I see is:
gfortran -c all_cp2k_gfortran.f90

Hi Joost,
I'll look into it. I now regularly build cp2k with gfortran (usually 4.2
branch) on i686-linux for my work but I haven't see this ICE yet. Just in case,

As far as I can see, the C++ front-end fails to call overflow_warning
(c-common.c) from build_binary_op (cp/typeck.c) in the same way as the C
front-end does in parser_build_binary_op(c-typeck.c).

Why this is marked as other ? This is either a problem on the C/C++
front-ends or it is a problem in the middle-end that doesn't handle the
overflow/underflow correctly during conversion, isn't it?
Also, this happens
The failures in the testcases gfortran.dg/char_transpose_1.f90,
gfortran.dg/matmul_2.f90, gfortran.dg/matmul_3.f90 are apparently due to a
miscompilation of the gfortran FE.
The error can be traced to the following code from trans-arrray.c:775

With following testcase gcc 4.1.1 with -Os produces two back-to-back jumps:
jump to L2 if less; jump to L2 if less-or-equal; the first one is not needed.

The miscompilation appears first with -O -ftree-vrp, i.e. removing -ftree-vrp
from the following command line gives a working executable, with it, we get a
broken compiler.

--- Comment #9 from steven at gcc dot gnu dot org 2006-11-25 22:24 ---
Why is this an fwprop bug? You haven't really shown that AFAICS. Could be a
latent bug elsewhere that fwprop uncovered. Or can you pin-point the specific
insns that fwpwop produces, and which you think is wrong?
The following code snippet triggers an ICE since GCC 3.3:
===
templatetypename T struct A
{
static const T i = 1;
int __attribute__((vector_size(8))) a[i];
};
===
bug.cc:4: internal compiler
The following invalid code snippet triggers an ICE on the 4.2 branch
and mainline:
===
struct A { typedef int X; };
struct __attribute__((unused)) A::X;
===
bug.cc:3: error: using typedef-name 'A::X'

The following example is a reduced testcase from icewm. GCC when configured for
ppc-*-linux-gnuspe segfaults.
To reproduce the ICE compile like below
g++ -c -O2 testcase.C
this works fine on gcc configured with powerpc-*-linux
testcase.C

This testcase shows the problem when compiled with -ffast-math:
double test1(double x)
{
double y1, y2;
y1 = sin(x);
y2 = cos(x);
return y1 / y2;
}
double test2(double x)
{
return sin(x) / cos(x);
}
gcc -O2 -ffast-math:

MAX_EXPR aWidthD.2267, aWidthD.2267

Reassiocation produces:
aWidth_29 = MAX_EXPR aWidth_7, aWidth_7;
w_30 = MAX_EXPR aWidth_29, iWidth_14;
From:
aWidth_29 = MAX_EXPR iWidth_14, aWidth_7;
w_30 =
