This array goes from 0 till 9

And here you go from 1 to 10. The reason it doesn't crash in one case 
and that it does crash in another case, is due to alignment differences 
(in the "crash case", your record is bigger, so there is more chance 
you will write beyond the boundary of allocated memory).
