             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_stasis
    Affects Versions: 18.0.1, 17.8.0

This is a follow up for ASTERISK-28931, which we opened some time ago. Seems like the same problem is happening again.

This problem started on Asterisk 17.3.0 and is happening in every version onwards. We are currently running version 18.0.1 and the segfault still occurs.

Our Asterisk instances are crashing at least one time per day with the following backtrace being displayed:
