Apparently destructors aren't the law in C++. The following code never calls ~B.
#include <iostream>
class A {
public:
virtual void print(const std::string s) = 0;
};
class B : public A {
public:
~B(void) {
std::cout << "Self-destruct." << std::endl;
}
void print(const std::string s) {
std::cout << s << std::endl;
}
};
int main(int argc, char ** argv) {
A * a = new B();
a->print("cows");
delete a;
return 0;
}% ./abstract
cows
%Now what? Using reinterpret_cast instead doesn't get it to work.
