[MPlayer-users] New CPU-detection code in current CVS, crash on Athlon

[Michael Mauch]

Hi,

after CVS update of today, MPlayer crashes shortly after caching the
first chunk of a (S)VCD. MPlayer worked great before with the same
(S)VCD (I'm sorry I don't know when I CVS updated before).

My system once was SuSE 6.1, but in the mean time I updated and built
almost everything from sources.

"--disable-runtime-cpudetection" doesn't help, neither does replacing the
old ~/.mplayer/codecs.conf.

"gcc -c -O4 -march=i486 -mcpu=i686 -pipe -ffast-math -fomit-frame-pointer" 
are the right flags for my Athlon?

Hope I didn't forget something.
