Comment (by cehoyos):
Please test two things separately:
First please test unpatched FFmpeg, run configure and then change the line
in config.h containing `HAVE_ALIGNED_STACK` into:
{{{
#define HAVE_ALIGNED_STACK 0
}}}
Then please test if this patch alone (without any other changes and
without changes to config.h) fixes the issue you see:
{{{
