Your pop<\/code> function destroys the entire stack. It deletes<\/code> the tmp<\/code> node (by calling the Stack<\/code> destructor), which still points to the new next<\/code>.
\nAnd since the Stack<\/code> destructor calls delete on next<\/code>, you get a mess of multiple destructor calls on the same objects.<\/p>\n

JMA<\/strong> beat me to it by a few seconds, so refer to their code fix for a quick solution.<\/p>\n

However, I would recommend you add a dedicated Node<\/code> struct instead of composing Stacks<\/code>, it will actually increase the clarity of your code.<\/p>\n<\/p><\/div>\n
