--- Comment #8 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Alternatively, compile with -fcheck-new to tell the compiler that *all*
operator new overloads can return a null pointer. That means it always checks
for null, even for overloads that are declared as potentially-throwing. This is
probably not what you want to do, you probably just need to use 'noexcept' in
the right places.
