[asterisk-users] Segmentation fault with 13.5.0 / PJSIP 2.4.5

[Recursive]

Dear colleagues,

I just have experienced a segmentation fault with Asterisk 13.5.0 and PJSIP 2.4.5. Both of them have been compiled on a standard Debian Wheezy 64 bit. I did not apply any patch or alter the sources of Asterisk or PJSIP in any way. Before compiling and installing, I removed all traces of all old Asterisk and PJSIP versions from my system very thoroughly.

The segmentation fault occurred when I was re-registering multiple endpoints one after another as fast as I could do it manually (by operating the respective phones) and at the same time tried to make calls from these phones. I have attached what was happening before the segfault in the CLI; I had started Asterisk with -vvvvvc.

Unfortunately, I can't reproduce the situation, so if we want to know the cause of the problem, I guess it's necessary that a developer analyzes the attachment and the respective part of the source code. I think I am not (yet ?) so deep in Asterisk that I could help debug the problem, but if anybody tells me what to do I am willing to help.

I hope that the attachment won't get blocked ...

Regards,

Recursive
