Not the behaviour I'm getting (I'm at 8.0 -- but I don't think this will have changed at 8.2).
the termination of the calculation didn't work
What do you expect to happen for "termination"? What do you expect for the types of the arguments (each of the three), and for the result? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14410#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

What's `WinGHCI`?
[https://code.google.com/archive/p/winghci/wikis/WinGhciFeatures.wiki GHC's answer to WinHugs]
I assume some wrapper around `ghci.exe`?
Yes, to a first approximation.
I think this is a duplicate of #14150.
Thank you. Yes, looks likely. (That would explain why I'm not seeing it at 8.0.)
Try the recently released `8.2.2` RC.
