[vlc-devel] libvlc_media_instance_release causing segfaults

[Enrique Osuna]

libvlc_media_instance_release (src/control/media_instance.c) was
causing segment faults.  I was able to trace it back to the
input_position_changed (src/control/media_instance.c) callback.  It
was trying to send an event to the event manager after the event
manager was freed.

I reviewed libvlc_media_instance_release and saw that the event
manager was one of the first sub objects to be released...the
input_thread was still alive and was trying to feed into the event
manager well after the event manager was destroyed.  I moved
release_input_thread before libvlc_event_manager_release (please see
attached).

Side note, I did pause the video (via libvlc_media_instance_pause)
before I called libvlc_media_instance_release, but the input_thread
kept updating the "intf-change" variable causing
input_position_changed to be executed.
