             Summary: [patch]Asterisk crashes if DAHDI mfcr2 channel is destroyed while in a call
                 Key: ASTERISK-24184
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24184
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_dahdi
    Affects Versions: SVN
            Reporter: Tzafrir Cohen
            Severity: Minor


I'm trying to work on disconnecting and reconnecting DAHDI MFC/R2 spans. This issue handles the simples form: manually destroying a channel while it is in a call. If it is not in a call, nothing seems to be wrong. If it is in a call, it crashes due to a segmentation fault. The attatched patch fixes the symptoms.

To reproduce:

1. Configure a DAHDI channel (say, 3) as an mfcr2 channel
2. Start a call through it.
3. From the CLI, destroy it:  dahdi destroy channel 3 3

Asterisk crashes immediately.
