[Mplayer-users] Segfault/Signal 11 in init_video_codec when loading win32 dll

[Slo Mo Snail]

Hi
I'm using a linux from scratch ;) with kernel 2.4.9, glibc 2.2.4, XFree86 
4.1.0, gcc 2.05.3, ld 2.11.2 and as 2.11.2

when i start mplayer and it needs a win32 dll it crashs with:
Loading DLL: /usr/lib/win32/divx_c32.ax
MPlayer interrupted by signal 11 in module: init_video_codec

but it doesn't crash only with divx movies but with every win32 codec :(

Maybe MPlayer needs some libs i don't have? But why is wine running pretty 
good?

when i run mplayer in gdb (i can't do a coredump... don't know why...  
perhaps because of the missing debugging symbols in all libs):
