#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): Ugh, that's not all. I tried to build our (big) project with [https://git.haskell.org/ghc.git/commitdiff/33452dfc6cf891b59d63fa9fe138b18cb... 33452dfc6c Refactor the Mighty Simplifier] GHC revision and it was still failing. So, I returned to the test example and was able to trigger the issue on GHC {{{master}}} branch by [https://github.com/4e6/webapp- template-hs/commit/d15ef703a61fd98202e475bff60609d0dd072f50 implementing some methods] and slightly increasing reader size. **Summary** [https://github.com/4e6/webapp-template-hs/tree/simpl-tick-factor webapp- template-hs] branch ''simpl-tick-factor''\\ Builds with {{{ghc-7.10.3}}}\\ Fails with {{{ghc-8.2.1}}} and {{{master}}} branch\\ [https://gist.github.com/4e6/5ef65efdb309daa373a928ec36404fd7 gist] with updated ''-ddump-simpl-stats'' output -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14338#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
