--- Comment #15 from Marc Glisse <glisse at gcc dot gnu.org> ---
I posted a patch:
http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00676.html

However, note that it only optimizes the testcase from this PR if we add
#include <new> at the beginning, otherwise the implicit declaration of operator
new doesn't have its operator_new_flag set...
