Just for the record: I'm not an FFmpeg developer (in case you got that 
impression), so I'm probably not competent to comment on this. However, 
the fix you propose looks wrong to me because code_table gets assigned 
to the global variable huff_code_table[i]. So we don't want to free this 
memory because it's going to get used well beyond the lifetime of that loop.
