The unref 'av_frame_free(&avctx->coded_frame)' was already added as part 
of commit 13e9cc9.
This is exactly what causes the crash. I doubt that there is a fate test 
for this, because that would have revealed the crash. For testing 
purposes you can use:
avconv -y -i ./tests/reference.pnm -c:v a64multi -f avi /dev/null
