             Summary: Segfault: ast_variables_destroy #channel_vars #set_var #sorcery_realtime
                 Key: ASTERISK-28649
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28649
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_realtime
    Affects Versions: 16.5.0, 16.6.2
         Environment: CentOS Linux release 7.6.1810 (Core) 
3.10.0-957.27.2.el7.x86_64

Asterisk build: asterisk-16.6.2
Alembic Version: 3a094a18e75b
            Reporter: John Bowen


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.
