[asterisk-users] Segmentation Fault Asterisk 13.7.0-rc2 (libmysqlclient?)

Hi everyone,

I am getting a segmentation fault (seems to occur randomly) using Asterisk 13.7.0-rc2 with PJProject 2.4.5. It appears to be something that libmysqlclient is complaining about when doing a query in ps_endpoint_id_ips. We are using Asterisk Realtime. This also seems to occur in Asterisk 13.5.0.


Below is a backtrace that might help a little. I have looked through the change log for the 13.7.0 release and some of items addressed may fix my problem. Before diving in and attempting to upgrade to the final version of 13.7.0, I was hoping someone with knowledge would be able to look at this and let me know if this is something already seen or if this is entirely new.


Thanks for the help!
