I'm aware of both bugs (found them indepedently while testing some more string
intrinsics) and have fixed them with my next patch (will submit in a few days).

CONFIRM. Due to the missing checking it works with openSUSE's 4.1, 4.2, 4.3;
however, if one studies the source code, it is also wrong in other 4.x besides
4.4. The current test case fails only on systems where

I have found a test case for the issue mentioned in comment #4. And it comes
from gcc itself:
static int *free_phinodes[10 - 2]; /* was 'tree' */
static unsigned long free_phinode_count;
void
init_phinodes (void)
{
For the i386 stack probing feature there is a non-standard argument register
%eax used for internal __chkstk call. If the code is translate with gcc with
optimization level one or less, code is fine. For -O2 and higher, the argument
%eax for __chkstk is optimized out.
The following source is a

This happens again on PPC. No test case yet.

Confirmed. This seems like a weird design to me, but my reading of the
standard text agrees with yours.

Sorry, I missed to install the new compiler :}
Yes, it works, assembler looks now fine.
Thanks, Kai

I have a patch which can handle this test case, see
http://gcc.gnu.org/ml/fortran/2008-05/msg00296.html
It's not complete yet, and some details need to be fixed, but the basic
functionality is there. I hope it can be

Can you please regtest the patch on your target?
BTW: Is this a regression for 4.3 and 4.4?
