Calling delete on variable allocated on the stack

Question

Ignoring programming style and design, is it \"safe\" to call delete on a variable allocated on the stack?

For example:

   int nAmount;
   delete &am         


        

Answer 1

You already answered the question yourself. delete must only be used for pointers optained through new. Doing anything else is plain and simple undefined behaviour.

Therefore there is really no saying what happens, anything from the code working fine through crashing to erasing your harddrive is a valid outcome of doing this. So please never do this.
