[saethlin]

This ICE is usually from a corrupted rmeta file. If you run cargo clean then cargo build, does the clean build succeed?

You filled out the issue template as if this can be reproduced by a clean build, but also your paste of compiler output is clearly not a clean build. If you encountered this while hacking on scallop, it is likely that this is some kind of incremental compilation state corruption issue. The incremental compilation system relies on both hardlinks and file locking working correctly, so it's quite possible that those features are subtly buggy on Haiku, or just work differently.
