[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: wine-bugs(a)winehq.org ReportedBy: sandalle(a)sourcemage.org 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).

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. :( $ gcc -v Reading specs from /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/specs Target: i686-pc-linux-gnu Configured with: /usr/src/gcc-4.4.3/configure --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man --enable-threads=posix --with-system-zlib --build=i686-pc-linux-gnu Thread model: posix gcc version 4.4.3 (GCC) $ uname -a Linux pangomer 2.6.33.2 #5 SMP Fri Apr 23 02:39:44 PDT 2010 i686 GNU/Linux (In reply to comment #2) 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. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
http://bugs.winehq.org/show_bug.cgi?id=22475 --- Comment #4 from Henri Verbeet <hverbeet(a)gmail.com> 2010-04-24 06:49:36 --- 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? -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
