When I attempt to enable the siptrace module in my configuration, I am presented with the following error and the core dump:

compiled on 18:15:23 Jul 20 2015 with gcc 4.4.7

Siptrace parameters set are:

modparam("siptrace", "db_url", DBURL)
modparam("siptrace", "hep_mode_on", 1)
modparam("siptrace", "trace_to_database", 1)
modparam("siptrace", "trace_flag", 22)
modparam("siptrace", "trace_on", 1)

I came accross the following archive mail thread where it mentioned that there may be some issues with the mi module when loading siptrace:

http://lists.sip-router.org/pipermail/sr-dev/2011-June/011417.html

I'm not sure if it is in any way related, but if it is, I am loading the mi_rpc module as well, however, I did not issue any commands over rpc to activate the above crash.

Let me know if you need any additional info from me to debug this further.
