But this is not the problem. Current libc declares:
void *memalign(size_t _align, size_t _amt);

and OpenJPEG uses the right argument order

#ifdef HAVE_MEMALIGN
extern void* memalign(size_t, size_t);
#undef opj_aligned_malloc
#define opj_aligned_malloc(size) memalign(16, (size))
#undef opj_aligned_free
#define opj_aligned_free(m) free(m)
#endif

The problem is if align is > 8, then it crashes :\

Maybe this is the cause why x264/ffmpeg crashed with enabled some inline asm optimized mmx/sse code that I disabled, long time ago, don't remember exactly...
