I never talk about legacy stuff. :-) I assume a modern compiler and in
particular I assumed Dev-C++.

Yes.

Yes, but without being required by the standard, most probably the program
would die directly upon the second deletion.



In any case we can make only assumptions without the code. And we can also
make observations. And I had observed old stuff, char *s, strcmp()s. As I
had pointed out in a previous email, replacing all char *s with std::string
is a good starting point.
