Re-opening the issue, as it has been incorrectly closed as WontFix. Out of Memory issues are valid bugs in most of the cases. WontFix status might be assigned only by the owner of the target code, if there is no way or no reason to prevent fuzzer from causing OOM crash. Sometimes we mark OOMs found with MSan as WontFix because MSan has big memory overhead. However, that should not be done without a proper understanding of the target as well as without looking at the crash stats.
