Summary:                    Asterisk crashes on reload of pbx_config.so
Description: 
After a recent upgrade from 1.2 to 1.4 we are getting intermittent crashes
when we issue a "reload pbx_config.so" from the asterisk console.  Notably,
our dialplan is quite large (http://bugs.digium.com/view.php?id=8#50MB).  This
did not appear to be a problem
under 1.2.  bt and bt full attached.  Since its not always re-producible,
I'm hoping that someone the bt will prove useful / informative to someone.

Well, my gut instinct is that this is some thread related thing. When the
dialplan gets big, it takes a long time to reload... and other things going
on at the same time....  the code is supposed to handle this well, but some
(imp)robable event might... well... cause a problem.

We'll see.

The backtrace says it died while "destroying" (freeing up) a context, and
an exten, and died in the free func. So, something is getting freed twice,
or mem is corrupted, or something...!

Is there any chance at all, that two reloads are being run in parallel? I
know, I know, I know, that should be safe....

Is there any way you can send, perhaps, a sanitized version of that 50 meg
of config file so we can see if we can reproduce the problem?
