Memory corruption while watching DVB

Hi,

I've just tried to watch some DVB-T and DVB-T2 channels via xine-lib-1.2, and the playback starts running into problems after a few minutes. I am suspecting memory corruption, particularly after it crashed like this:

*** Error in `xine': double free or corruption (fasttop): 0x00000000021441d0 ***
xiTK received SIGSEGV signal, RIP.


A rudimentary bisection via repeated use of "hg update N" suggests that the first bad commit is:

description:
Add avformat demux plugin.
   - Support for new formats and protocols.
   - Proper rtsp support (with avformat+rtsp://, rtsp+tcp:// and rtsp+http:// mrls).
   - by default native xine demux plugins are probed first.
     This can be overridden in config, by selecting demuxer in mrl (#demux:avformat),
     or by using "avformat+" mrl prefix.


In a separate issue, xine is also crashing almost immediately when I enable interlacing while watching a DVB-T MPEG2 channel. However, interlacing seems OK with DVB-T2 MPEG4 channels.

Cheers,
Chris
