The problem occurs frequently but not reliably.  Starting asterisk service
usually causes one or more segfaults before safe_asterisk successfully
starts asterisk.

---------------------------------------------------------------------- 
The attached extensions.ael has been pared down from my original
configuration, but still results in the same segfault sometimes upon
service asterisk restart or ael reload.  The sample extensions.ael provided
by 'make samples' does not seem to segfault.
