I have checked CDVDOverlayCodecTX3G::Decode and there is nothing
obviously wrong with it.
Based on the stack trace I suspect there was a memory allocation issue
somewhere else in the code where the memory pointed to by the reported
invalid pointer has been freed.
Could you please test latest version from unstable?
If the issue still exists please run xbmc under valgrind to let us able
to find the place where the invalid free occurs.

Cheers,
Balint
