can anyone explain why this code gets AC ?

#include <stdio.h>

void ASS(bool b)
{
    if (!b)
    {
        while(1);;;
    }
}

int main()
{
    ASS(0);

    int a, b;
    scanf("%d %d", &a, &b);
    printf("%d\n", a + b);

    return 0;
}

And where is a bug? This code works on my computer too. :)

but it must be TLE, the bug of course not in test system,
bug is in the compiler VS2010.
