#11608: Possible type-checker regression in GHC 8.0 when compiling `microlens` -------------------------------------+------------------------------------- Reporter: hvr | Owner: simonpj Type: bug | Status: closed Priority: highest | Milestone: 8.0.1 Component: Compiler (Type | Version: 8.0.1-rc2 checker) | Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHC rejects | Test Case: valid program | typecheck/should_compile/T11608 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Hm. These `ASSERT`s used to be here, and I removed them because they were triggering on kind variables, which were not always `TcTyVar`s. However, if the `dependent` set of tests in the testsuite aren't failing here, then perhaps things improved from when I removed the `ASSERT`s. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11608#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
