#13474: GHC HEAD regression: Prelude.!!: index too large -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): I would be happy to. Unfortunately there are some testsuite issues in Phab:D3316 which will need to be resolved before it can be merged. Namely, `T11480b` fails with, {{{ T11480b.hs:131:10: error: • Couldn't match kind ‘*’ with ‘Constraint’ arising from a use of ‘T11480b.$dmop’ • In the expression: T11480b.$dmop @Constraint @(:-) In an equation for ‘op’: op = T11480b.$dmop @Constraint @(:-) In the instance declaration for ‘Category (:-)’ }}} which I'm reasonably confident will break user code (namely Edward Kmetts's `constraints` library). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13474#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
