New subject: [Users] Crash (core)

25 Jan 2006


      Hi Lars,
it took some time, but thanks to your details debug output I was able to 
trace the problem and fix the bug. As I was expecting, in was in the 
to/from parser.
Please update from CVS and give it a try.
Thanks again for the help,
bogdan

I wish I could, but the INVITE's are not logged and I have not been 
able to reproduce the problem on the test system :-( so i realize this 
isn't very easy to "fix" I was mainly checking if this was a known 
problem.
Version is 1.0.0-tls (disable_tls=0) compiled from source.
uac is called like:
   uac_replace_from("SomeText: $avp(s:display)","")
The INVITE was most likely produced by a "Aastra Intelligate" SIP UA 
since the particular customer has one of these registered right now.

Hi Lars,
can you please post the complete INVITE request that produces the 
crash and how the uac_replace_from() function is called from script? 
and what version are you using?
regards,
bogdan

I have switched from SER to OpenSER in our production enviroment 
since I
need a few of the "new" modules, I am however having troubles with
OpenSER hanging and crashing, so much so, that I had to change back.
There is no clues in the logs to why this is happening but i have a
coredump from a crash:
