[SR-Users] segmentation fault when mongodb & tls enabled. ( kamailio 4.3.2)

[Jijo]

I'm observing a segmentation fault when mongodb & tls enabled. It doesn't
happen when one of the module is disabled.
OS: centos 6.7   kamailio 4.3.2  mongo-c-driver version 1.1.10.

It happens immediately after i register a subscriber. The location table is
updated with the new data and in parallel core is generated as well.
