Hello!
During playing around with route headers I discovered that ser crashes reproduceable when I send the following request to it with sipsak, I think the invite is a valid request with strict routing.

Hello,
could you, please, generate a core dump ? Use ulimit -c 1000000 to enable core generation and reproduce the crash. Then compress the compiled sources along with the core dump and send it to me.
thanks, Jan.

Hello,
I wasn't able to reproduce it, but I think I know where the problem is. There is a bug in 0.8.10 which shows up when an INVITE contains Route header field. The bug has been fixed in the CVS already.
If you can compile ser from sources, you can easily fix it in your release:
1) Edit ser-0.8.10/modules/tm/t_msgbuilder.c 2) Jump to line 103 3) replace len+= with *len+= 4) Recompile ser
I can send you a patch if it is more convinient for you.
regards, Jan.
