This issue has been raised just recently on the gcc-help mailing list.
See the thread:

I've just searched for "uninitialized missing" and got 22 bugs, some of
them seem to look related to yours, although I haven't checked/compared
the details.  In the worst case you can just file the bug and it will be
marked as duplicate eventually (if it is one).
