vp8 threaded encode crashes on mingw (experimental and master branch) #580

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
From #x264dev: vp8 encoding in both master and experimental is broken with -t N 
where N > 1. The problem is that it doesn't re-align stack on the initial 
function entry in each worker thread, and then the first function that uses 
aligned stack data crashes. This can be fixed by marking the initial function 
that is called from pthread_create() with 
__attribute__((force_align_arg_pointer)) on gcc>=4.2.

This also causes libvpx 1.3.0 to crash if cross compiled with mingw.
Patch to add
  __attribute__((force_align_arg_pointer))
for *-win*-gcc targets.
