Summary:                    Core Dump on 1.4.24 - local_pvt_destroy
(pvt=0x193cbc00) at chan_local.c:159
Description: 
I had a server core dump on me tonight.  I have been running 1.4.21.2
without issue for a long time.  I upgraded to 1.4.24 about a month ago and
just had the problem for the first time.  The server had less than 100
calls up when the problem occurred.  Based on the fact that we do a few
hundred thousand calls/day and this is the first time this happened in a
month, I am pretty sure I won't be able to reproduce this on-demand.

Please let me know if there is anything else I can provide.  I have
attached 3 different bt outputs as well as the relevant dial plan as
referenced in the back trace.

The dial plan is executed by using a manager Originate to a Local channel
which then passes control off to a SIP channel.

Thanks!

just looking at some code here.   could this occur if for some reason pvt
is null when it's passed to free()?  I would think ast_mutex_destroy would
fail if pvt was NULL, but what do I know :)  I write Java, this manual
memory management is for the birds!


/*!
 * \note Assumes the pvt is no longer in the pvts list
 */
static struct local_pvt *local_pvt_destroy(struct local_pvt *pvt)
{
        ast_mutex_destroy(&pvt->lock);
        free(pvt);
        return NULL;
}
