#10527: Panic Simplifier ticks exhausted with type families -------------------------------------+------------------------------------- Reporter: sopvop | Owner: bgamari Type: bug | Status: new Priority: highest | Milestone: 7.10.2 Component: Compiler | Version: 7.10.1-rc1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by bgamari): One obvious qualitative difference between the two simplifier trajectories is that the 7.10.2 stops emits its last `SimplBind` trace (for `$s$crsubset_s2gQ`) somewhere around 13% through the log (measured in lines). In contrast, 7.10.1 emits `SimplBinds` every regularly (at most every few hundred lines) throughout the log. I suppose this means that 7.10.2 is spending most of its time playing with this one top-level binding? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10527#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
