Hey thanks for the report.

The issue here is a timeout:

[grz harness][Mon, 22 Jul 2019 22:20:15 GMT] Test case time limit exceeded
[grz harness][Mon, 22 Jul 2019 22:20:15 GMT] Closing test case

This will only happen when --fuzzmanager is used since there is no stack trace available to create a CrashInfo object. This is expected although not perfect. The workaround is to either ignore timeouts using --ignore timeouts or don't use --fuzzmanager. Note this will happen anytime a stack trace is not available to parse or if parsing a stack trace fails. Only the latter case is a real issue.

--ignore timeout works for me. Thanks!
