#14338: Simplifier fails with "Simplifier ticks exhausted" -------------------------------------+------------------------------------- Reporter: dredozubov | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by 4e6): Ok, I [https://github.com/4e6/webapp-template-hs/tree/simpl-tick-factor pushed] the update that removes almost all external dependencies. With this update, I was able to build the project with latest ghc-8.3-start-1211-g82b77ec375 (version by git-describe) Interestingly enough, ghc-8.3 doesn't show the presence of the bug. It means that the regression was fixed after the ghc-8.2.1 release. I also updated the [https://gist.github.com/4e6/5ef65efdb309daa373a928ec36404fd7 gist] with ''-ddump-simpl-stats'' output for all three ghc versions. Total ticks number for ghc-8.3 is similar to ghc-7.10.3 value. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14338#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
