I'm not sure if it's strictly a bug (against the spec), or if you're relying on
an implementation detail when you assume construction at the destination.
Either way, I agree that it's weird how adding a temporary makes the copy go
away. I see a reasonable enhancement request, at least.

You can reopen issues yourself. However, in this case I think we better open a
new one. Did that here: issue 15842. I've added you to the CC list.

If there's anything else going on, could you provide a test case where that's
more obvious? Or maybe point out how the additional corruption is visible in
the code samples we have so far.
