The solution I propose covers most of the use cases (the ones it doesn't cover are for object of a type that has virtual bases or virtual functions). Unless you are doing something really sketchy, it will make a lot of existing code well defined.Sent from my Samsung Galaxy smartphone.

I am sure most of us remember how in the early 2000s most C++ programmers did not care whether their code had UB but were instead adhering to a sort of unofficial standard where e.g., something like dereferencing a null pointer would be illegal, but violating strict aliasing is A-OK....We have to maintain very large code-bases built upon this edifice. Not only do we need a solution, we need one that can be mechanically implemented.________________________________IMPORTANT: The information contained in this email and/or its attachments is confidential.
