Oh, I think that this code has such a path. We already know that the
code I showed is entered when that error is set. So the solution would
be to put SetError(0) before the call to CreateFileMapping(), possibly
before both such calls.
Maybe we need to look at all the places we call GetLastError(). There
are quite a few of them.
Good catch, BTW.
