--- Comment #20 from Pedro Alves <palves at redhat dot com> ---
And in addition, since GCC is already using new/new[] to heap allocate its own
classes, GCC is _already_ inconsistent with allocation failure -- if one of
those currently fails, you'll end up with a C++ exception that nobody is
catching, so GCC dies a horrible death.  Replacing operator new of course would
handle those too.
