Why is returning a pointer to a local variable a logical error?
Local variables automatically fall from scope when a function returns. If the function returns a pointer to one of its local variables and you subsequently attempt to dereference that pointer, you introduce undefined behaviour into your program. With undefined behaviour you have no way of knowing what will happen: the program may work; the program may crash; the program may wipe the user's hard-drive. Anything can happen when you introduce undefined behaviour into a program.

What is a segmentation fault?
An error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers in the source code, dereferencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.
