--- Comment #3 from reid.kleckner at gmail.com <reid.kleckner at gmail.com> ---
I'm sorry, I should try reading the diagnostic.  That's about returning bool. 
Ignore my comment.

The derived foo method does not get the noreturn attribute and we don't warn
about it, but we do assume that all implementations of foo are noreturn at the
call site.

Clang should probably be changed to either not assume that or warn on method
overrides that aren't also noreturn.
