Something like this

int res() { return -1; } 

void check()
{
        int i;
        if ( (i=res()) < sizeof(i))
                return;
        printf("Mmm... this is a bad compiler!\n");
}

Calling check() print "Mmm... this is a bad compiler!", but -1 <
sizeof(i) should be true !!! My knowledge of C tell that conversion
unsigned int -> int is implicit, so compiler should convert sizeof(i) to
int and compare. It seem that first convert i to unsigned int and then
do compare...
