#12919: Equality not used for substitution -------------------------------------+------------------------------------- Reporter: int-index | Owner: goldfire Type: bug | Status: patch Priority: highest | Milestone: 8.4.1 Component: Compiler (Type | Version: 8.0.1 checker) | Resolution: | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHC rejects | Test Case: valid program | typecheck/should_compile/T12919 Blocked By: | Blocking: 14441 Related Tickets: #13643 | Differential Rev(s): Phab:D3848 Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): For the record: this patch should fix this ticket, #13643, #13822, #14024, #14126, #14038, #13910, #13938. It's hard for me to say how it affects #14441, but Simon's analysis suggests that the problem stems from this ticket as well. The ticket is held up because of some performance trouble, but we'll get it in eventually. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12919#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
