@EricWF When switching to `__libcpp_operator_{new,delete}` everything gets compiled exactly the same on my system. Could you disclose which test you used for this code? You also claim that the `__pointer_int_pair` causes the optimizer to lose track of the function pointer causing the call to not be elided, but I can't see any calls other than `new` and `delete` in the code you posted either.
