Modular arithmetic bug?

GHC dies here (please note the x < 200 limit): take 15 [x | x <- [1..], x < 200, x mod 6 == 1, x mod 6 == 5]

And here (nothing with infix notation): take 15 [x | x <- [1..], x < 200, mod x 6 == 1, mod x 6 == 5]

But *not* here: take 15 [x | x <- [1..], mod x 6 == 1, x < 200, x > 100]
