I've observed this behavior as well. From what  can tell, it's a 
false positive that only shows up in the presence of previous 
error. I'd say that has something to do with the way the compiler 
do semantic analysis. My money is on the fact that `core.atomic` 
is special, and that something else (bad error gagging, perhaps?) 
triggers an error. As far as I can tell, it is safe to ignore.

If you can reduce it to something small enough, I'd say it's 
worthy of an issue tho.
