Thank you, the path to the modules was the problem!
Now ser runs also as self compiled version and doesnt crash. I didn't had to change the source because the source code available to download is already corrected. To proof your guess I inserted the error again ( len+=) and than it crashes again.
Conclusion: with the source code version from 0.8.10 ser doesn't crash anymore. Nevertheless, /var/log/messages shows an error message when I send my special invite:
Feb 6 15:48:24 obelix /usr/local/sbin/ser[6985]: ERROR: t_build_and_send_CANCEL: cannot allocate memory
thanks and regards, Klaus

Double check path of the modules. Probably you are using config file from the rpm package, after make install the modules will be in /usr/local/lib/ser/modules. The rpm package installs them in /usr/lib/ser/modules so you will have to change it.
There is no uninstall in the makefiles, you can uninstall only by hand right now.

Hello!
I have problems running the self compiled ser version (without any sourcecode changes).
I uninstalled the rpms ("rpm -e ser-mysql" and "rpm -e ser" - I use the mysql authentication). Then I compiled ser with "make
all" without
errors. I installed ser with "make install". Then I tried
to start ser
with: # /usr/local/sbin/ser -f /etc/ser/ser.cfg ERROR: bad config file (25 errors)
Why does my config file doesn't work anymore (it worked
with the rpm
version)? When I start ser with -f, than it starts (but than it doesn't use the mysql database).
Have I done something wrong during the installation/compiling?
How can I delete the files that were installed by "make
install"? make
uninstall?

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:
- Edit ser-0.8.10/modules/tm/t_msgbuilder.c
- Jump to line 103
- replace len+= with *len+=
- Recompile ser
I can send you a patch if it is more convinient for you.
regards, Jan.

That's the bug I told you about, AFAIK it is caused by the missing dereference operator in t_msgbuilder.c. See my previous email for description how to fix it. (rewrite len+= to *len+=, recompile and reinstall).
