How has this slipped through?
Answer: AVIOContext starts with an AVClass* that is unset when using
ffio_init_context(). Therefore the av_freep() leads to freeing of a NULL
pointer which does not segfault.
Would setting s->av_class to &ff_avio_options in ffio_init_context()
prevent this from happening again?
Btw: This patchset is based upon code inspection, not on reading
actual files.
