#9117: Coercible constraint solver misses one -------------------------------------+------------------------------------ Reporter: goldfire | Owner: nomeata Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by goldfire): Your non-terminating `Foo` example seems pathological, but what about this, somewhat more sensible example: {{{ newtype Bar a = Bar (Either a (Bar a)) x :: Bar Age x = coerce (Bar (Left (5 :: Int))) }}} This example works in 7.8.2. PS: Will contribute to the "Coercible" page in due course. Thanks for starting it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9117#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
