[Bug 22475] New: Compiline WINE with '-mfpmath=sse' in CFLAGS/CXXFLAGS on x86 causes segfaults

http://bugs.winehq.org/show_bug.cgi?id=22475

Summary: Compiline WINE with '-mfpmath=sse' in CFLAGS/CXXFLAGS
                    on x86 causes segfaults
           Product: Wine
           Version: 1.1.43
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

If you compile wine with '-mfpmath=sse' in CFLAGS and CXXFLAGS, games such as
Dungeons and Dragons Online (free-to-play, but not open source, so somewhat
easy to test with), Lord of the Rings Online, and EVE Online all segfault when
trying to load.

Running a basic command such as `wine iexplore` does not segfault.

I did not get any debugging information when I tried this, sorry. Removing
'-mfpmath=sse' and recompiling WINE (used WINE 1.1.43, GCC 4.4.3, GNU LibC
2.11.1) removes the segfaults. Note that '-mfpmath=sse' is enabled by default
on x86_64 (see
http://gcc.gnu.org/onlinedocs/gcc-4.3.4/gcc/i386-and-x86_002d64-Options.html).

CFLAGS/CXXFLAGS used:
-march=native -mtune=native -m32 -pipe -DPIC -fPIC -O2  -mmmx -msse -msse2
-mssse3 -msse4.1

You missed the most important part - gcc version. Post output of 'gcc -v'.

Finding a small download (with source available) or better yet a builtin wine
program that exhibits this would help greatly.

I said, "(used WINE 1.1.43, GCC 4.4.3, GNU LibC 2.11.1)" in the middle of a
paragraph, not making it easy to find, sorry. :(

I'll try and find a more testable app to reproduce this bug and, hopefully, the
actual place it segfaults and the error, but that may not be gotten to
immediately.

Does Wine itself segfault, or throw an exception? If it throws an exception, is
that an access violation or a floating point exception? Does this also happen
with current git?

That's a gcc bug.
