I'm going to push the patch in ~10 min since I don't see it pushed yet.

I agree that it looks like a regression, but it might be tricky to
retrieve the function name from the stack. I'm not even sure that the
function name is always already on the stack.

Again, I have to rush before of the feature freeze, but I hope that we
will find a smart solution for this error message.
