mmoroz: Can you remind me how bad it is to have fuzzers run out of memory? I don't think I can fix this without reducing the maximum supported image size.

It's pretty bad in general, but this crash has been found with MSan, which has a significant memory overhead, so please feel free to WontFix if it doesn't happen with ASan. One more important signal though is how often this crash occurs. There is Crash Stats section on the ClusterFuzz page, stats for that one don't see terribly bad, but don't look insignificant either. How bad it would be to reduce the maximum supported image size, as you mentioned in c#5?
