Comment (by terran):

 I've found that the bug will trigger for me when these two params are
 modified from their defaults:

 -sc_threshold 40
 -qmin 0

 For example, if I hold sc_threshold at 40, I can raise qmin from 0-5. 6+
 fails. And if I hold qmin at 0, I can lower sc_threshold down to 1.

 Were there threading/instruction set/etc changes that relate to either of
 these params in the last couple of months? Could either of these somehow
 affect libfaad or muxing?
