Hello !
Using LLVM/Clang 3.3 as of now (r172971) at -O3 :

$  cat assert.c
int a, b, c, d, k, **g;

void f(void)
{
    int e;
    long h;

    for(;; e++)
    {
        for(; a; a++)
            for(; b; b++)
                k && (a |= 0) && d && h != (e ? : d) ? **g = 0 : (c = h += k);

        for(; k; k++)
        {
            long *q = 1;
            e /= *q && (c ? *q : b);
        }
    }
}
