-- This one actually crashed in 6.4.1
-- There's a kind error in the signature for bar,
-- and we were recovering, and then crashing when we found
-- a scoped type variable not in scope
data Val v sm = Val
foo :: forall v sm. Val v sm
foo = undefined
where foo1 :: Val v sm
foo1 = bar
-- Correct type signature: bar :: forall v sm. Val v sm
bar :: forall v. Val v
bar = undefined foo
`Val v' is not applied to enough type arguments
Expected kind `*', but `Val v' has kind `* -> *'
In the type `forall v. Val v'
In the type signature for `bar':
bar :: forall v. Val v
