Comment (by TheSHEEEP):

 I disabled sse (--disable-sse, sse2 and sse3) to see if that was the issue
 and I think it is not. I do now get a crash in the same function
 (swri_audio_convert), but the part that is called when sse is not
 available:

 {{{
 ctx->conv_f(po+off*os, pi+off*is, is, os, end);
 }}}

 And conv_f seems to point to this:


 {{{
