There were no changes to this code in the timeframe of the bug. I looked through the crash reports and nothing stood out to me. If we don't see similar failures on other builds, I'm inclined to believe it was an issue with the build itself. Maybe some sort of PGO issue?

The fact that there is a single build-id definitely hint to a compilation issue.
We should reopen this bug if this bug re-appear in the future.
