You could easily get a segfault *if* the memory is big enough (> 1 page)
*and* if there is some support from the OS. Remove the RW permissions from
the page and when somebody wants to access it or write it... BOOM! You'll
get your segfault.

So it's not only lucky, so can choose your own destiny ;)
