#9070: "Simplifier ticks exhausted" -------------------------------------+---------------------------------- Reporter: dermesser | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+---------------------------------- Comment (by DinoMorelli): carter: The project is epub-metadata. Available on Hackage, but I have already released a newer version with adjusted -fsimpl-tick-factor, so get the prior version: {{{ $ cabal unpack epub-metadata-4.0 }}} The error says: {{{ When trying UnfoldingDone base:GHC.Base.build{v 04} }}} Still fails with just -fno-full-laziness, but the message changes to: {{{ When trying UnfoldingDone hxt-9.3.1.4:Control.Arrow.IOStateListArrow.$fCategory*IOSLA_$c.{v rzUB} }}} Also, I'm not specifying any -O switches at all, I'm not sure what the default optimization level is for GHC. simonpj: I was wondering about that, if this is normal-ish and just requires params. Do you need me to provide more details here, perhaps with `-ddump-simpl- stats` ? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9070#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
