#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): I've updated [https://github.com/4e6/webapp-template-hs/tree/simpl-tick- factor webapp-template-hs] example (branch ''simpl-tick-factor'') to be compatible with GHC 7 and 8. With ghc-7.10.3 it compiles with 2534 simplifier ticks, and with ghc-8.2.1 it panics with 'Simplifier ticks exhausted' on 256649 ticks. See readme for details. Here is the full `-ddump-simpl-stats` output for both cases: https://gist.github.com/4e6/5ef65efdb309daa373a928ec36404fd7 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14338#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
