When the exception is thrown, then during the stack unwinding process, I think only local objects are destroyed, not static or heap objects. If this is true, I am not sure why the class (test) destructor is called? Thanks.
The test destructor is called after main exits.
catch(int k)
{
cout<<"exception handler"<<endl;
}
// Added this line
std::cout << "Main Exiting\n";
}
Now testing
> g++ test.cpp
> ./a.out
constructor called
exception handler
Main Exiting
destructor called
Static (static storage duration objects) are destroyed in the reverse order of creation after main exits.
