Bug#408256: asterisk-chan-capi crashes Asterisk (Asterisk exited on signal 11, Segmentation fault)

[Len Padilla]

Package: asterisk-chan-capi
Version: 0.7.1-1
Severity: important


Hello,

I've been using Asterisk (testing) 1.2 branch for some time with fcpci
kernel module for an AVM Fritz! PCI ISDN card, chan_capi compiled from
0.7.1 source and several SIP channels. I saw that asterisk-chan-capi had
been upgraded to 0.7.1 so I installed it. SIP calls work fine, but
incoming CAPI calls crash Asterisk. Reverting to the
compiled-from-source version of chan_capi.so makes everything work fine
so I'm pretty sure the packaged version of chan-capi.so is somehow the
culprit.
