Whenever a pointer consists of entirely ASCII character codes, you know you
overran a buffer somewhere with a strcpy() or strcat() or sprintf() etc.

So you take the results of printing those character codes and see where
they could be generated in your code.

Since a character code is one byte, that's two hex digits and you use GDB
to cast that to a (char) so you can see the character.

Hence my demonstration with the 8 letters being printed from his GDB
