#12993: GHC 8.0.2-rc2 template Haskell interface file issue -------------------------------------+------------------------------------- Reporter: glguy | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2-rc1 Resolution: | Keywords: Operating System: MacOS X | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by glguy): The issue seemed to be that the the AlexTools module is using the `runA` record selector from Template Haskell but that that record selector is not exported to preserve an abstraction boundary https://github.com/GaloisInc/alex-tools/blob/master/src/AlexTools.hs#L268 If I export runA, or define runA as a top-level definition (even without exporting it) the bug does away. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12993#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
