--- Comment #24 from Richard Biener <rguenth at gcc dot gnu.org> ---
Well, fact is we still don't have the machinery that warns for the use of
uninitialized memory - and we never had.  The cases that work by
accident are for loads that alias-analysis can prove we can move to
the function entry (well, a little less than that).
