The '%' (mod) operator causes programs to lock up

[rebeccabuckingham]

Have noticed that when I use the '%' operator, that my program crashes. I've reproduced this in a small test:

printf("before trying mod\n");

int a = 10;

printf("after assigning a, before b\n");

int b = a % 9;

// this line never gets printed printf("b is now %d\n", b);
