#10715: Possible regression in Coercible a (X a) between 7.8 and 7.10 -------------------------------------+------------------------------------- Reporter: inaki | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): I'm all for !ForeignPtrs having distinct types. I just don't understand why it has to be a recursive type. What's wrong with this? {{{ newtype FY = FY (ForeignPtr Y) data Y }}} (except that it isn't what c2hs does today) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10715#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
