I'm using the ghc 6.8.2 package distributed with Ubuntu. I tested haddock with the haddock package itslef. I also installed the haddock2 documentation found at http://code.haskell.org/~fons/libraries.html-haddock2.tgz in order to get links properly. The following listing contains how to reproduce the bug. First I install haddock, then I try to generate the haddock documentation of haddock itself. When I realize that the documentation directory is empty, I run the exact haddock command called by Cabal and I realize that the command segfaults. I also attached an strace listing od the segfoulting command in case it helps. {{{ alfonsoa@s1395:~/haddock-2.0.0.0$ ghc --version The Glorious Glasgow Haskell Compilation System, version 6.8.2 alfonsoa@s1395:~/haddock-2.0.0.0$ PATH=$HOME/bin:$PATHalfonsoa@s1395:~/haddock-2.0.0.0$ ./Setup.lhs cleancleaning...alfonsoa@s1395:~/haddock-2.0.0.0$ ./Setup.lhs configure --user --prefix=$HOMEConfiguring haddock-2.0.0.0...alfonsoa@s1395:~/haddock-2.0.0.0$ ./Setup.lhs buildPreprocessing library haddock-2.0.0.0...Preprocessing executables for haddock-2.0.0.0...Building haddock-2.0.0.0...[1 of 4] Compiling Haddock.Exception ( src/Haddock/Exception.hs, dist/build/Haddock/Exception.o )[2 of 4] Compiling Haddock.Types ( src/Haddock/Types.hs, dist/build/Haddock/Types.o ) [3 of 4] Compiling Haddock.InterfaceFile ( src/Haddock/InterfaceFile.hs, dist/build/Haddock/InterfaceFile.o ) [4 of 4] Compiling Distribution.Haddock ( src/Distribution/Haddock.hs, dist/build/Distribution/Haddock.o ) /usr/bin/ar: creating dist/build/libHShaddock-2.0.0.0.a [ 1 of 24] Compiling Haddock.Comments ( src/Haddock/Comments.hs, dist/build/haddock/haddock-tmp/Haddock/Comments.o ) [ 2 of 24] Compiling Haddock.Backends.HH ( src/Haddock/Backends/HH.hs, dist/build/haddock/haddock-tmp/Haddock/Backends/HH.o ) [ 3 of 24] Compiling Haddock.Backends.HH2 ( src/Haddock/Backends/HH2.hs, dist/build/haddock/haddock-tmp/Haddock/Backends/HH2.o ) [ 4 of 24] Compiling Haddock.Utils.BlockTable ( src/Haddock/Utils/BlockTable.hs, dist/build/haddock/haddock-tmp/Haddock/Utils/BlockTable.o ) [ 5 of 24] Compiling Haddock.Utils.Html ( src/Haddock/Utils/Html.hs, dist/build/haddock/haddock-tmp/Haddock/Utils/Html.o ) [ 6 of 24] Compiling Haddock.Backends.Hoogle ( src/Haddock/Backends/Hoogle.hs, dist/build/haddock/haddock-tmp/Haddock/Backends/Hoogle.o ) [ 7 of 24] Compiling Haddock.GHC.Utils ( src/Haddock/GHC/Utils.hs, dist/build/haddock/haddock-tmp/Haddock/GHC/Utils.o ) [ 8 of 24] Compiling Paths_haddock ( dist/build/autogen/Paths_haddock.hs, dist/build/haddock/haddock-tmp/Paths_haddock.o ) [ 9 of 24] Compiling Haddock.Version ( src/Haddock/Version.hs, dist/build/haddock/haddock-tmp/Haddock/Version.o ) [10 of 24] Compiling Haddock.Exception ( src/Haddock/Exception.hs, dist/build/haddock/haddock-tmp/Haddock/Exception.o ) [11 of 24] Compiling Haddock.Types ( src/Haddock/Types.hs, dist/build/haddock/haddock-tmp/Haddock/Types.o ) [12 of 24] Compiling Haddock.InterfaceFile ( src/Haddock/InterfaceFile.hs, dist/build/haddock/haddock-tmp/Haddock/InterfaceFile.o ) [13 of 24] Compiling Haddock.Utils ( src/Haddock/Utils.hs, dist/build/haddock/haddock-tmp/Haddock/Utils.o ) [14 of 24] Compiling Haddock.Options ( src/Haddock/Options.hs, dist/build/haddock/haddock-tmp/Haddock/Options.o ) [15 of 24] Compiling Haddock.GHC.Typecheck ( src/Haddock/GHC/Typecheck.hs, dist/build/haddock/haddock-tmp/Haddock/GHC/Typecheck.o ) [16 of 24] Compiling Haddock.GHC ( src/Haddock/GHC.hs, dist/build/haddock/haddock-tmp/Haddock/GHC.o ) [17 of 24] Compiling Haddock.Interface.Rename ( src/Haddock/Interface/Rename.hs, dist/build/haddock/haddock-tmp/Haddock/Interface/Rename.o ) [18 of 24] Compiling Haddock.Interface.AttachInstances ( src/Haddock/Interface/AttachInstances.hs, dist/build/haddock/haddock-tmp/Haddock/Interface/AttachInstances.o ) [19 of 24] Compiling Haddock.Interface.Create ( src/Haddock/Interface/Create.hs, dist/build/haddock/haddock-tmp/Haddock/Interface/Create.o ) [20 of 24] Compiling Haddock.Interface ( src/Haddock/Interface.hs, dist/build/haddock/haddock-tmp/Haddock/Interface.o ) [21 of 24] Compiling Haddock.ModuleTree ( src/Haddock/ModuleTree.hs, dist/build/haddock/haddock-tmp/Haddock/ModuleTree.o ) [22 of 24] Compiling Haddock.Backends.DevHelp ( src/Haddock/Backends/DevHelp.hs, dist/build/haddock/haddock-tmp/Haddock/Backends/DevHelp.o ) [23 of 24] Compiling Haddock.Backends.Html ( src/Haddock/Backends/Html.hs, dist/build/haddock/haddock-tmp/Haddock/Backends/Html.o ) [24 of 24] Compiling Main ( src/Main.hs, dist/build/haddock/haddock-tmp/Main.o ) Linking dist/build/haddock/haddock ... alfonsoa@s1395:~/haddock-2.0.0.0$ ./Setup.lhs install Installing: /home/alfonsoa/lib/haddock-2.0.0.0/ghc-6.8.2 Installing: /home/alfonsoa/bin Registering haddock-2.0.0.0...
