          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2

Backtrace

I have just compiled Wine with the following CFLAGS:

-march=native -O2 -pipe -ftree-vectorize (which on my PC translate to
-march=atom -mcx16 -msahf -maes -mpclmul -mpopcnt -msse4.2 --param
l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=4096
-mtune=core2)

using recently released GCC 4.5.0.

Now all non-native applications fail to start.

In future please find a better place to file this kind of bugs. If you believe
that if someone miscompiles Wine code that's a Wine bug, then something is very
wrong with your logic.

Dmitry, I vividly remember bug 2488 which was indeed a wine's problem, rather
than GCC's one, so I posted this bug thinking that there's a subtle bug in
Wine's code.

If you tell me to refrain from posting GCC related bugs I'll do so.

Of course it's very nice that you remember a bug you reported 6 years ago.

However it's pretty strange that you have filed bug 22377 and bug 22385
which have been resolved as invalid with direct link to the gcc bug, and
then you report this bug 22387. Marcus in the Comment #1 clearly said once
again what's the source of the problem, and even after that your memory can't
recognize some "vaguely similar" symptom of the problem?
> If you tell me to refrain from posting GCC related bugs I'll do so.

Just a suggestion though, if you prefer for some reason to use your own
custom compilation flags (although it's been stated many times that it's
not recommended) with a bleeding edge gcc, then you could at least take
some efforts to investigate the problem on your own, not dump it on somebody
else's shoulders right away.

Point taken - I'm going back to GCC 4.2.4 which has never caused any problems
for me.

BTW, I'm not using any extreme GCC flags, for the last few years I compile all
sources either with:

C   Compiler flags: -march=pentium2 -O2 -pipe -ftree-vectorize
C++ Compiler flags: -march=pentium2 -O2 -pipe -ftree-vectorize
Linker flags: -Wl,-O1 -Wl,--hash-style=gnu -Wl,--enable-new-dtags

or with:

C   Compiler flags: -march=native -O2 -pipe -ftree-vectorize
C++ Compiler flags: -march=native -O2 -pipe -ftree-vectorize
Linker flags: -Wl,-O1 -Wl,--hash-style=gnu -Wl,--enable-new-dtags

Anyway, it looks like GCC is kinda degrading because these innocuous flags
cause some much stir, however Linux kernel works nicely having compiled with
the aforementioned flags (albeit without -ftree-vectorize).

Artem, does gcc-4.5.1 behave any better for you?
If not, does -mstackrealign help?

crash log

No, all applications still crash and I'm using not yet releases GCC 4.5.2 from
SVN ;)

I will now try to use -mstackrealign flag.

OK, -mstackrealign solves this problem.

PS Meanwhile I just don't compile wine using -ftree-vectorize any longer.
