Yes.

I think we should try to do better when assigning a location to new
function decls,
that is, avoid UNKNOWN_LOCATION and at least have some file information.
For cilk-plus functions using the decl location of the original
function might work.

That said, a safe-guard against this case is ok, thus the patch is as well.
