---------------------------------------------------------------------- 
I'm thinking memory corruption, possibly related to running out of C stack
space.  Both Macro and AGI are rather hungry for stack, relative to other
apps.  We can fix the direct cause of the crash, but there's less we can do
about the memory corruption without running Asterisk under valgrind and
finding the root cause of that.  If the C stack is the culprit, we might
look into giving you the opportunity to use more stack per thread, or
reducing the stack footprint of AGI and/or Macro.
