Your parenthesisation is bad: in this form, no compiler could
accept it.
printf("%d %d\n", ((int)(a))-((int)(b)), ((int)(a))-(int)(b))) > 1 );
1 23 33 32 23 33 32 23 33 32 2 22 210 -1
I'm not suggesting that this is your entire problem; but why don't

re-write this line, and try it again? Then post the results.
