Summary:                    [patch] Crash in do_monitor() in chan_dahdi.c
Description: 
I'm unable to reproduce but have a core file of Asterisk 1.6.0.10 of a
crash in chan_dahdi.c. It looks like `iflist` may have been modified
somewhere else without a lock though I'm not positive (see Additional
Information or attached file).

I have MALLOC_DEBUG, DONT_OPTIMIZE, DEBUG_THREADS and DEBUG_CHANNEL_LOCKS
enabled.

I'm running Asterisk 1.6.0.10 on linux:
[root ~]# cat /etc/redhat-release 
Fedora Core release 3 (Heidelberg)
[root ~]# uname -a
Linux pbxtra1063 2.6.9-1.667 https://issues.asterisk.org/view.php?id=1 Tue Nov 2
14:41:25 EST 2004 i686 i686 i386
GNU/Linux

I've attached a full backtrace. Please let me know if there is any more
info I can provide.
