************************* UNREPRODUCIBLE *************************
Note: This crash might not be reproducible with the provided testcase. That said, for the past 14 days, we've been seeing this crash frequently.

It may be possible to reproduce by trying the following options:
- Run testcase multiple times for a longer duration.
- Run fuzzing without testcase argument to hit the same crash signature.

If it still does not reproduce, try a speculative fix based on the crash stacktrace and verify if it works by looking at the crash statistics in the report. We will auto-close the bug if the crash is not seen for 14 days.

When you fix this bug, please
* mention the fix revision(s).

* add any other useful information.
