#14338: Simplifier fails with "Simplifier ticks exhausted" -------------------------------------+------------------------------------- Reporter: dredozubov | Owner: bgamari Type: bug | Status: new Priority: high | Milestone: 8.4.1 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 mpickering): I think this regression is caused by https://git.haskell.org/ghc.git/commitdiff/1722fa106e10e63160bb2322e2ccb830f... I built a compiler which comments out the relevant two lines from that patch and the number of ticks for n=10 is around 1500 vs 75000 for an unpatched compiler. So, relevant tickets are #13032 and #11230 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14338#comment:28 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
