--- Comment #10 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-11-26 11:36:56 UTC --- For example, consider this variant of the PR53661 situation: enum class Code { SUCCESS = 0 }; Code a; short r[] = {a}; we currently produce a -Wnarrowing warning, which seems bogus to me, exactly because we don't realize that actually the only enumerator has value zero.
