Be sure I will :) Thanks Man! 2011/5/21 Giovanni Maruzzelli <gmaruzz@gmail.com>:
No need for a Jira, because I fixed it in git.
It's not related to network.
A skype interface was receiving a DTMF without a channel on it. That was causing a segfault (my code expected a channel).
Now it will not segfault anymore, it will just give a warning.
I was curious why there was no channel. Maybe a channel was destroyed (hangup, cancel, etc) at the same time the skype client was getting the dtmf...
Anyway, is fixed now. Please update to latest git.
Please keep up reporting bugs and issues, that's the way to have an ever improving software.
Thanks, -giovanni

Problem it's not easy to reproduce that. I't working on production PC, as a skype gateway to an asterisk host, serving a bunch of users. As per recommendations, after the first segfault I've recompiled the FS with no optimization, and dumping the core. Not sure That I can produce guidelines to reproduce the given. Since I have the core, we can trace it deeper, though. I can add that it happen already 5-6 times, and maybe related to fail of the network link to neighboring ASTERISK box, while in conversation. But anyway not sure though. Atleast once it failed without any network failure, with similar backtrace. Seems it's necessary to analyze the segfaulting function.

Anyway, I just added some guards that will avoid the crashes, but I would still very interested in the procedure to replicate the problem.
Please, let me know how you got this problem, also if it does not bite you again.

Please open a Jira issue with all related info, particularly how to reproduce this bug and a debug listing.
Important is that you give a clear way to reproduce the bug, ie: a step by step way to have the same result (crash in this case).

Giovanny, I've got several segfaults of FS, seems they belongs to SKYPOPEN
