[MPlayer-users] Bug with x86-64

[Aaron Williams]

I compiled MPlayer 1.0 pre 7 on my Athlon64 and am getting a crash when 
I try and use the v4l2 driver with my capture card.  I compiled 
everything for 64 bit and am running SuSE 9.3 professional.

I compiled with mmx, mmx2, sse, sse2, 3dnow and 3dnowex since all should 
be supported on my Athlon64 (which also supports sse3).  The crash 
appears to be somewhere in the mmx code.

Here's the crash information:
