This tests an previously erroneous case in the pattern compiler. It was assuming that the variables bound in a guard matched the variables bound in the rest of the branch exactly, but apparently this needn't be the case.

f w = w + x
match t with
(x, y)
| y < 5 -> f x
| otherwise -> x + y
> foo (10,20)
