Hello,

The crash happen once. it can't be reproduced. The pai seems good, why it cannot be parsed?

apparently it was parsed, but then the content got reset. The sip_msg_t for request is accessed via a callback inside acc module when the sip_msg_t for response is handled.

So I have to see why it got reset, it shouldn't -- the patch so far was to prevent the crash.

Hello,

for the moment I added a safety check to prevent crash in such
situation:
-
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=e633ca6b7e748a77825d3208e86bf9bce18944a5

I need to investigate more to discover why the parsed field has
null content.

Does the crash happen often or can it be reproduced?

Cheers,
Daniel

Hello,

I missed somehow the message with the pai parsed content. I will
look over it later today.

Cheers, Daniel

Hello,

Do you any ideas about the reason of this issue?
Is it caused by the last call? Do you have enough information
with the PAI?

Regards,

Igor.
