[SR-Users] segmentation fault in init_mod_child function

[Bruno Bresciani]

Hi All,

Kamailio 3.1.2 terminated with signal 11, segmentation fault, in the
init_mod_child function at sr_module.c file. This problem occurs only when
I try loading the loadbalance.so module, it was written by me.

Someone Can help me to understand why this segmentation fault was
generated? There are two other module written by me and this problem
doesn't happen.

Kamailio's trace:
