It seems to still be the case that print026 sporadically fails:
{{{

I saw this commit by Ian a while back:
{{{
commit 5e95d99276e754a12279b909ab6365c262e80da1

Skip print026 in the 6.8 branch
It fails for me, but not consistently - possibly only with a validate
build. Seems plausible that the problem is something like library
build
flags.
-l = Data.Sequence.Seq (Data.Sequence.Deep 3
- (Data.Sequence.One
(Data.Sequence.Elem 'a')) Data.Sequence.Empty
- (Data.Sequence.Two
(Data.Sequence.Elem 'b') (Data.Sequence.Elem 'c')))
+l = <Data.Sequence.Deep> (<Data.Sequence.One> 'a')
<Data.Sequence.Empty>
+ (<Data.Sequence.Two> 'b' 'c')
}}}
So this is probably not some deep bug, but we ought fix up the test case
to work in all cases. (I can't tell if this is a containers problem or a
GHC problem.)
