Bug#698112: asterisk: Segfault when making a call after update to 1.6.2.9-2+squeeze9

[Dennis Rech]

Dear Mr. Cohen,

after the update to squeeze9, the asterisk process restarts fine. When 
someone does a SIP call, the asterisk process immediately terminates 
with the described segmentation fault (according to dmesg). As the 
software is running on our production server infrastructure, I have 
performed a downgrade to squeeze8 again to ensure proper operation 
during our office hours. That's also the reason why I won't be able to 
upgrade again and debug the system now because I have to keep the 
telephony operational during office hours.

Maybe I can reproduce it with a test system, I'll keep you informed.

Regards,

Dennis Rech
