caps->hasMMX2 = caps->hasSSE; // SSE cpus supports mmxext too
looking at i386/machdep.c, there is no MMX2 cpu flag and i dont see
anybody talking about MMX2 (although the mplayer sources are full of it)
only SSE[1-4].
i am afraid i have no idea if an unsupported instruction can
generate "Program terminated with signal 11, Segmentation fault."
or some other fatal error. but MMX being so old, i'd say
the instruction set is supported.
the other filter i have been using and can't reproduce a crash so far
is fspp=0. libmpcodecs/vf_fspp.c has one single #if HAVE_MMX2,
it seems to be more of an MMX filter.
i have no /etc/malloc.conf
hope this helps.
