We've had a crash report, and we found it during the investigation. (The reason why I opened it as draft was because I wanted to find code paths like this (e.g, the return value of a function that may fail is used without checks), but some of them are not that straightforward to validate, so I will merge this PR, and open a separate one for those.) |
