(btw, these *are* bytes -you own, even if you didn't ask for all of them, so it's correct code -to access all of them if you want.) Unfortunately, the Windows CRT -_recalloc() routine assumes that _msize returns exactly as many bytes -as were requested. As a result, _recalloc() may not zero out new -bytes correctly.
