[asterisk-ss7] chan_ss7 0.8.4 crashes with asterisk 1.2.13

[Kai Militzer]

Hello everyone,

I just tried to update my systems with chan_ss7 0.8.4 to the latest
asterisk release 1.2.13 but somehow there seems to be a change in
asterisk that let's chan_ss7 crash asterisk when a call from SS7 gets
in. Luckily I have a coredump, as I will not be able to reproduce this
failure or try different things, as the system is in production. Maybe
someone has an idea what changed that breaks things, as I can't find
anything on my first look, but I will continue searching.

The backtrace looks like that:
