(Reasonable) In the case of self-assignment, a go assignment operator mustn't depart the object Keeping pointer users which have Get More Information been deleted or established to nullptr.

The strings of v are wrecked upon exit from lousy() and so is v by itself. The returned pointer details to unallocated memory to the no cost retailer.
