Summary:                    Hard crash in send_packet (Asterisk
1.2.33-BRIstuffed-0.3.0-PRE-1y-u)
Description: 
Asterisk has hard crashed. The pertinent stack trace line is:
https://issues.asterisk.org/view.php?id=0  0x00007fbe772fb48b in send_packet
(f=0x7fbe6dd7e960) at
chan_iax2.c:1760
poking around in the source from gdb:

(gdb) p f->callno
$1 = 12554
(gdb) p iaxs[f->callno]
$2 = (struct chan_iax2_pvt *) 0x0

Which is the obvious culprit.

This seems odd given that only 9 lines earlier (chan_iax2.c:1751):

if (!iaxs[f->callno])

So the iaxs array seems to have been modified in the intervening time.

As noted in the title, the version we are running is:

Asterisk 1.2.33-BRIstuffed-0.3.0-PRE-1y-u
