asterisk users - Jul 2007 - Asterisk 1.4.6 crash using queue app

I'm using Queue app with Asterisk 1.4.6

It was working 5 days without problems and then it crash.
When I did #gdb asterisk core.xxx
I see...

There is some weird stuff in that backtrace which makes me think it is not 
accurate.  You have to build without optimizations to get a good backtrace.  So,

1) Update to the latest version - currently 1.4.8

2) If you still have a problem, disable optimizations

$ make menuselect
Compiler Flags -> DONT_OPTIMIZE
'x' to save and quit

3) Run Asterisk with the -g option and retrieve the backtrace (both bt and bt
full).

4) Post the backtrace to bugs.digium.com with as much information as you can 
regarding your configuration, console output before the crash, as well as any 
other information you can provide about what was going on when it crashed.
