If I was guessing, I'd say that the channel structure that is being
modified by the ast_setstate() call is incomplete, and contains some
garbage pointers.

If I was guessing further, I'd say that the callerID pointers are the
most likely candidate - Does the issue happen when a caller-id
withheld call is hung-up? hung-up before being answered perhaps?

You'd need to add some debug reporting into ast_setstate() to know for sure.

Just my 2p - 1.4.42 is an old version, so the chance of a solid answer
is fairly low.
