thanks for the report. I’m not sure what to do about it though. Is there
a fix available? Also, you file this against the stable version, while I
do not expect a fix for this to be worthy of backporting to stable. Is
it fixed in 7.8, or in 7.10?

I think this is clearly an upstream matter. Can I suggest you take this
discussion upstream at https://ghc.haskell.org/trac/ghc/ticket/703?

Thanks,
Joachim
