I have use cases which would be a lot easier to implement if shared_from_this() never throws. And - at least with the "old" implementation - I don't see any reason why this guarantee should not hold. Of course it's not a defect, but to me it seems desirable.
It is technically possible to make it throw without violating the functions documented requirements, if there are multiple owners. For example, if pass the raw pointer to multiple shared_ptrs with null deleters.
Could you provide a small but complete code example, please? I fail to see how that case should be legal. Regards, Daniel
