asterisk users - Dec 2006 - Core Dump: create_transaction (p=0x0) at pbx_dundi.c:2787

Anyone seen this...? Is it a known issue?

I'd file a bug, but we're on 1.2.9.13, and every time I file a bug and
it isn't against the latest code I get given crap for it. Given that most of
the time you don't know HOW to reproduce a problem on the latest code
anyway, not accepting bugs from older versions does the community no service,
because potential bugs are never accepted for submission.

Hmmm, that will be a tricky one to track down. There's no reason to get
a core dump from within malloc() unless something else has previously
stomped outside of its own malloced area, smashing the free list.

So the problem is likely not within create_transaction(), but caused
sometime before, possibly in some completely unrelated code.

Is it repeatable, or just happens at random (or even just once)?

Cheers
Tony
