sorry I missed that.
had a look and though bt says *ppktl = is the line, due to optimization, Id
tend not to believe it.

If it happens again, jack,
as well as the bt for that thread,
need
inf reg
disass av_find_stream_info

this appears to be a 64bit build too.

I think your patch would be pointless.
be better to put in an invalid check explicitly just before the write, or if
you want to catch the error completely in cas it happens
put a try/catch around the call to av_find_stream_info in avformatdecoder
(c++ exception handling). Ive used this trick a few times where Im using 3rd
party libs which arent as good as they should be.
nothing guaranteed and cant see how its happening without a stray ptr in
another thread blamming things.
cheers
