[Serdev] SER crashes

[Jorge Crichigno]

Hi all,

   I have a problem with SER 0.9.0. I'm running it with 2 little
modifications:

    1- I add a parser for Reason Header (for supporting RFC 3326.
Although it is very simple, I can give it to who wants it). When parsing
this header, I just use the body field of hdr_field structure (hf.h)
(the field parsed is not used).

    2- I add an int field and and array field of fixed length to the
struct sip_msg (just as a test). 

  With these modifications, I run SER, and sometimes it crashes for a
reason that I didn't determine. The log showed was:

------------------------------------------------------------------------
It seems that SER crashed when the sip_msg structure was being released.
Can someone give me a hand?


Thanks in advance!!!
