I believe the sample code has UB. Array delete isn't polymorphic, you can't
delete an array of S2 objects as a pointer to an array of S objects. Consider
how this would go wrong for a two-element array when sizeof(S2) != sizeof(S):
struct S { virtual ~S(); };
struct S2 { virtual ~S2() { __builtin_printf("asdf\n"); } int grow; };
int main() { delete [] static_cast<S *>(new S2[2]); }
