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.

This one seriously breaks asterisk.

I have this in my extensions.ael:
if ( "${CALLERID(num):0:2}" = "31" ) {
    Set(CALLERID(num)=0${CALLERID(num):2});
}

and it gets loaded as:

4. GotoIf($[ "${C?5:6)                        [pbx_ael]
5. Set(CALLERID(num)=0${CALLERID(num):2})     [pbx_ael]
6. NoOp(Finish )                              [pbx_ael]
