I think you skipped the bug description template (were you not signed in to github? there is a github bug which they still have not fixed that skips the supposedly required template in late-signin cases): https://github.com/DynamoRIO/dynamorio/issues/new?assignees=&labels=&template=bug_report.md&title=

There's nothing actionable here: no description of how to reproduce; no description of when this happens (the callstack is truncated: when is this called? at process init time, thread init time, from a clean call during execution??).
