My experience is the following:

Line 109 in t_msgbuilder.c:

len += USER_AGENT_LEN + CRLF_LEN; ==> ser crashes when I send the special invite!

*len += USER_AGENT_LEN + CRLF_LEN; ==> ser doesn't crash but logs this in /val/log/messages: Feb 6 15:48:24 obelix /usr/local/sbin/ser[6985]: ERROR: t_build_and_send_CANCEL: cannot allocate memory

hope my explanation is a little bit clearer now: i also downloaded ftp://ftp.berlios.de/pub/ser/0.8.10/src/ser-0.8.10_src.tar.gz and this tarball contains: *len += USER_AGENT_LEN + CRLF_LEN;

ser-0.8.10_src.tar.gz has this bug too.

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).
