[Freeswitch-users] crash stack interpretation

[Brian West]

Can you reproduce the issue?   Running under Valgrind could by itself  
cause this to happen depending on your hardware.  Can you try to get  
it to crash without valgrind?  Be sure to set "ulimited -c unlimited"  
before you start freeswitch so we can get a valid core file to inspect.
