This is very odd, you define 3 variables, m, n and o.  But they are of
different type:

m - pointer to point
n and o - are  point

Secondly, you assume that they form a c-array of 3 elements.  However
you only defined 3 separate variables, not a c-array.

So the fact that it does not crash is luck. 
You ran out of luck in your second version.
