When building the stack guard, it has been traditionally important to have the
value start (in memory) with a zero byte to protect the guard value (and the
rest of the stack past it) from being read via strcpy, etc.

This patch reduces the number of random bytes by one, leaving the leading zero byte. https://www.kildarehousebuilders.ie
