#649 opensips crashing when excuting b2b_logic extern script

[tito cumpen]

Opensips is crashing 1 execute a fifo command like so "opensipsctl fifo b2b_trigger_scenario 3pcc sip:nurse@ip sip:patient@ip." Attached is the scenario file. The Ip addresses have replaced with IP. i am using the latest 1.9 stable release acquired via svn

Heres the entire backtrace

The patch is for trunk, but it's pretty much the same for 1.9.

Fix pushed in trunk and 1.9 branch.

[tito cumpen]

the recommend modifications were made now opensips is functioning as expected without the crash. I will try the latest branch as well. Please reach out to me @ tcumpen@icancerhelp.com to proceed with bounty.

Thanks a bunch.
