Given that it turns working code into UB, I think my preference is to gate it on a fix for the lowering bug, but I'm also not certain I am the right person to implement that fix (though I could give it a shot).


The test in question has a comment pointing to PR7117, which in turn indicates that we might miscompile parts of FreeBSD if we land this as-is. So I think we need to gate this on a fix for the lowering bug.
