             Summary: res_pjsip_pubsub: crash when subscription_destructor is terminated from a non-PJSIP thread
                 Key: ASTERISK-22953
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22953
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip, Resources/res_pjsip_pubsub
    Affects Versions: 12.0.0-beta2
            Reporter: Matt Jordan


When Asterisk is shut down, the pbx core will destroy the existing hints. This can cause a call to destroy_hint, which trigggers subscription_destructor from an Asterisk thread. Because this isn't synchronized over to a PJSIP thread, PJSIP throws an assertion causing a crash.

See attached backtrace.

Note that this was caused by the pjsip/ami/show_subscriptions test, although it certainly doesn't happen on every execution.
