I'm getting the same thing with WMV files with WMA2 audio.
It looks like the assembly in ff_imdct_half_sse is trashing something,
and so when it calls ff_fft_dispatch_sse it actually ends up in
ff_imdct_calc_3dn2.
I have 24 sample videos that fail like this, all with WMA2 audio.
One such sample is http://samples.mplayerhq.hu/A-codecs/WMA2/raam28mb.wmv

gdb session output attached with full symbolic backtrace.

Changing configure to use 'yasm -f macho' fixes it for me too.
ffmpeg/ffplay also use 'yasm -f macho' and does not have this problem
(ffplay can play these files fine).
