New subject: [Serusers] ser crashes

6 Feb 2003

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;

regards,
klaus

 Hello,

  Thank you, the path to the modules was the

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

  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  
   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).

     regards, Jan.
