Comment (by cehoyos):
The problem is that before sws_scale() gets called from scale_slice(),
out[0][-1] contains the offset for mem_align_hack from the aligned to the
originally allocated position. This value gets overwritten in sws_scale()
leading to an invalid address being used later for free().
