--- Comment #26 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- I just fail to understand why we cannot just clobber the whole object once in the in-charge constructor, then if sanitizing vptrs initialize every vptr once to zero. and skip all the clobber and vptr initializing on the not in-charge constructors. That would make just more sense. Bernd.
