On my machine (using Gentoo i686) wine crashes every time when trying to run for example DX-Ball 1.09 (free download http://www.magicwandsoft.com/games/dxball/ ) if it's compiled with both -mfpmath=sse (or sse,387) and -msse2 or higher cflags enabled. I mean: CFLAGS="-O2 -mfpmath=sse -msse" WORKS CFLAGS="-O2 -msse -msse2 -msse3" WORKS CFLAGS="-O2 -mfpmath=sse -msse -msse2" DOESN'T WORK CFLAGS="-O2 -mfpmath=sse,387 -msse -msse2" DOESN'T WORK CFLAGS="-O2 -mfpmath=sse -msse -msse3" DOESN'T WORK So for x86 wine ebuild should append flag -mfpmath=387. Furthermore, gcc on x86-64 defaults fpmath to sse, so someone could check if DX-Ball runs on x86-64. Then, if it crashes also on x86-64, I think that it's a bug in Wine and should be reported upstream. Reproducible: Always Steps to Reproduce: 1. CFLAGS="-O2 -mfpmath=sse -msse -msse2" CXXFLAGS="${CFLAGS}" emerge -1 wine 2. install DX-Ball 1.09 3. try to run it Actual Results: When compiled with -mfpmath=sse and -msse2, Wine crashes with some apps, notably DX-Ball.
we dont protect people from themselves wrt -mfpmath
