Illegal hardware instruction generated when using labelled breaks and missing return statement

Odin version: dev-2021-12:6ce56080 OS: macOS Monterey 12.0.1 (llvm 13)

Following code compiles (notice missing return statement) but crashes with illegal hardware instruction when run.

package bug

main :: proc() {
	s := foo()
}

foo :: proc() -> (result: int) {
	loop: for {
		break loop
	}
}

Adding return at end works, however (even though using named return parameter).
