[GHC] #8941: Module that causes GHC-7.8 to exhaust memory compiled with -O2
#8941: Module that causes GHC-7.8 to exhaust memory compiled with -O2 ------------------------------------+--------------------------------- Reporter: guest | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc2 Keywords: | Operating System: Linux Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+--------------------------------- The module is JSON.Render in http://src.seereason.com/o2bug. When compiled ghc uses up at least 16GB of RAM and then dies. I haven't been able to simplify it very much, almost any change to JSON.Render causes it to start working properly. I did get it to fail using only packages available in hackage. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8941 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I temporarily fixed it by adding a `-fno-spec-constr` option, maybe you want to try that as well? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8941#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
