Bug#448171: I'm having the same issue....

[Len Padilla]

When I dial in to asterisk from PSTN (I'm using a BRI connection with  
a Fritz!PCI card) and attempt to get to voice mail by pressing "*"  
during the outgoing message, Asterisk crashes:

Core was generated by `/usr/sbin/asterisk -f -p -g -U asterisk -vvvg - 
c'.
Program terminated with signal 11, Segmentation fault.
