Summary:                    Bug with iax channel (and perhaps IAXmodem) :
randomly crashes asterisk
Description: 
In one of my installations, asterisk randomly craches. This seems to be
caused by the chan_iax2 channel that I'm using with iaxmodems peers (used
by a hylafax server).

In case of, here is the modem configurations (located on the same
machine):

Iaxmodem side

device /dev/tty3955
owner uucp:uucp
mode 660
port 4570
refresh 60
server 127.0.0.1
peername 3955
secret fax3955
cidname <CID_NAME_OF_MODEM>
cidnumber <CID_NUMBER_OF_MODEM>
codec alaw

Asterisk side (iax.conf)

[3955]
type=friend
username=3955
secret=fax3955
qualify=yes
host=dynamic
port=4570
transfer=no
context=<DEFAULT_CONTEXT_USED>
disallow=all
allow=alaw

I've not recompiled asterisk with "optimisations disabled" for the core
dump trace, because it is a production system, but if it should be
necessary, I'll do it.

OS : Centos 5.1
