(the 'impossible' happened) (GHC version 7.10.1.20150601 for x86_64-apple-darwin): Simplifier ticks exhausted When trying RuleFired Class op bound To increase the limit, use -fsimpl-tick-factor=N (default 100) If you need to do this, let GHC HQ know, and what factor you needed To see detailed counts use -ddump-simpl-stats Total ticks: 1668404 Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10491#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
