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.

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.
