> Using sorcery realtime, if the column ps_endpoints.set_var` contains more than 16 characters a segfault occurs during the loading of endpoints. 
> This, however, does not occur when statically defining endpoints in pjsip.conf.
> Reproduce with:
> 1) Create three endpoints (odbc, realtime)
> 2) UPDATE ps_endpoints SET set_var = 'abc=1234567890abc' WHERE id is NOT NULL
> 3) Reload asterisk
> Notes:
> - All 3 endpoints must have channel_vars > 16 characters, the issue is not reproducable if only 2 endpoints have channel_vars > 16 chars
> - This issue was not present in 13.17.2 (using pjsip bundled)
> I'll be posting my findings as I dig into the code, but wanted to make core and other users aware of the issue first.
