#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 bgamari): To reproduce this with `HEAD` you will first need to install cabal-install from HEAD (this will only be a few minutes): {{{ $ git clone git://github.com/haskell/Cabal $ cd Cabal $ cabal install Cabal/ cabal-install/ }}} Now you can reproduce with, {{{ $ git clone git@github.com:bgamari/webapp-template-hs.git $ cd webapp-template-hs $ export ghc=$PATH_TO_GHC $ cabal new-build -w $ghc --only-dependencies $ n=9 ./build.sh -O1 -fsimpl-tick-factor=1000 -v -dverbose-core2core \ -ddump-to-file -dsuppress-ticks -ddump-simpl-stats \ -dsuppress-idinfo -dsuppress-coercions }}} There is also a `./build-all.sh` script which builds all `n`s from 1 to 9, dumping the output of each compiler run to a directory of the form `./dump-$n/`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14338#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
