IMO it shouldn't happen -- using the address after the memory is freed
is almost always a mistake, unless you're doing something like
1. free memory
2. search through array of pointers and delete any other references.
however i don't see any compelling reason not to do that in the other
order, or any reason for ffmpeg to do that at all..
