[OpenSIPS-Devel] Segmentation fault on startup

Thu Apr 18 11:36:44 EDT 2019

I'm attempting to check my config with opensips -c -f opensips.cfg and it crashes loading the tracer module (when it tries to query the table version - FYI mysql runs and I can access it with the opensips credentials and successfully query the table version from a mysql client):
