Answer 1

They don't cause a problem as long as they are not furtherly called to perform some action. The main issue is that most of the time they ARE called, motivating a memory corruption and hence an error or a crash.

If you're using a PC with Windows, here's an analogy: you may think that a pointer is kind of a shortcut in your desktop, which indeed references a program. If you delete the program, the shortcut itself points to "nothing", and then the shortcut is useful no more.

Answer 2

Man......

even all memory space is empty...!
