thanks for these examples. Both, though, give different error messages
in GHC HEAD. I’m more and more confident that this is an inadvertent
error message, see
https://ghc.haskell.org/trac/ghc/ticket/8592

Once that is sorted out, I’ll make sure these examples (or at least a
representative one) makes it into the testsuite.

Greetings,
Joachim
