--- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Florin Iucha from comment #2) > It indicates that it reports errors via exceptions. Yes, but that doesn't mean 0 is a valid return value. The non-nothrow forms of operator new also use exceptions to report errors, but that doesn't mean that they can return 0 as a valid pointer. pmr::memory_resource is intended to work the same way: either return a valid pointer to dereferencable memory, or throw an exception. There is no third alternative, of returning an invalid or null pointer value.
