You are writing to some random memory location, and the reaction varies
dependant on the operating system and/or hardware.

One thing to point out is that pointers and arrays are _not_ interchangable
entities _except_ when you are passing them to functions.  The moral is this:
when you mean to use a pointer, use a pointer; when you mean to use an array,
use an array.
