Catch runtime error for out of bounds array access

[curiouskiwi]

Example: Declare a char array: char cipher[strlen(p)]; and then later, try to set cipher[strlen(p)] = '\0' which is one past the end of the array. error: vigenere.c:56:17: runtime error: index 2 out of bounds for type 'char [strlen(p)]'

Actually, this is already handled by the server.
