The executable it produces should give that error. I've just compiled the
code you gave on my x86 Linux box and it is also segmentation faulting.
The lines 'p = k;' (using a shallow copy constructor) and 'p = person
("Bob", 10);' (shallow copying a temporary structure) are causing the
problems you are seeing. Because of char array you need a deep copy
constructor and also you'll need to overload the '=' operator. Otherwise
all you are doing is copying the memory address of the string. When main
goes out of scope the destructors are called. The name will effectively be
deleted twice in either case which is bad and will cause a segmentation
fault just like the following code will.
pointer = new char;
delete pointer; // intentional for the point I'm making
