Summary:                    conference calling crashes Asterisk
Description: 
I have a reproducible situation which crashes Asterisk. Conference calls
can be started, but as soon as anyone leaves the conference, or anything
else happens to initiate a soft hangup, it segmentation faults.

It's happening on both my test servers, running the following config:

Centos 5.2 (ISO's from centos.org, then fully yum updated)
Asterisk 1.6.0.3 AND latest SVN code (rev# 169479)
FreePBX 2.5.1
DAHDI 2.1.0.3 (installed from dahdi-linux-complete)

Everything is pretty much vanilla. A couple of extensions on each box, and
an IAX2 trunk between the two. One VoIP line on one of the boxes as the
main inbound/outbound route.

No telephony hardware, so it's using dahdi_dummy for timing. I've
confirmed with dahdi_test that this seems to be functioning correctly, and
lsmod and modprobe both look good.

I've tried doing a soft hangup from the CLI on regular calls, but that
works fine, no errors. It only seems to be conference calls which have this
issue.

This happens with any type of call in the conference, i.e. local
extension, coming in thru the IAX2 trunk, or inbound routes.
