#15095: pretty-show's literate haskell Setup.lhs failed on 32-bit windows -------------------------------------+------------------------------------- Reporter: simonmic | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.2 Keywords: | Operating System: Windows Architecture: x86 | Type of failure: GHC rejects | valid program Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- On appveyor I had a problem building pretty-show: {{{ -- While building custom Setup.hs for package pretty-show-1.7 using: C:\sr\setup-exe-cache\i386-windows\Cabal- simple_Z6RU0evB_2.2.0.1_ghc-8.4.2.exe --builddir=.stack-work\dist\ba067387 build --ghc-options " -ddump-hi -ddump-to-file" Process exited with code: ExitFailure (-1073741819) }}} More details at https://github.com/yav/pretty-show/issues/27 . Converting the (otherwise standard) Setup.lhs to a non-literate Setup.hs seemed to fix it. Switching to 64-bit GHC seemed to also fix it (the Setup.lhs worked with 64-bit GHC). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15095 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
