Summary:                    Crash on deeply nested while/if statements in AEL
Description: 
While reloading ael via ael reload the asterisk process runs into SIGSEGV.


This bug is curios since Asterisk starts and loads the ael very well. Also
if ael reload is typed in at the cli when starting Asterisk with -c is
working fine.

The issue only shows up when using asterisk manager or asterisk -r.

---------------------------------------------------------------------- 
I'll be looking into this. Interesing. 20 levels deep in if's, about 24
levels deep in match_pval... At the outset, it could be a stack overflow
issue (Asterisk has hard stack size limits), or it could just be a bug in
the match_pval stuff. I'll try and see. Give me some time, I'm up to my
neck right now in other issues.
