[Bug tree-optimization/38964] New: TBAA side-effects of C++ new still missing

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The TBAA side-effects of C++ operator/expression new are still not properly
(read: conservatively correct) handled.  The current implementation idea of
dealing with that in a flow-insensitive way is going to severely pessimize
optimization.

See http://gcc.gnu.org/ml/gcc-patches/2009-01/msg01212.html and followups.
