Comment (by simonpj):
I know what is happening. Sadly, it's in the middle of a `TcSimplify`
swamp that is in any case being overhauled as part of the type-function
story.
A workaround is to use `-XRelaxedPolyRec`, or `-XNoMonoPatBinds`. I think
that should make `CGS` compile ok.
But I will still try to fix for 6.8.2.
