#8406: Invalid object in isRetainer() or Segfault -----------------------------------+-------------------------------------- Reporter: crockeea | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Runtime System | Version: 7.8.3 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -----------------------------------+-------------------------------------- Comment (by pallly): In the time of writing my first comment I was using Gentoo Linux, I have just managed to reproduce the problem using Arch Linux (synchronized today). Here is how I did it: * `cabal sandbox init` * `darcs get http://hub.darcs.net/pallly/hdur` * `darcs get http://hub.darcs.net/komadori/HsQML` * `cabal sandbox add-source HsQML/` * `cabal install hdur/ --enable-executable-profiling --enable-library- profiling` * `.cabal-sandbox/bin/hdur +RTS -hr` After spawning the last command the application mostly crashes within a second. If it doesn't, I press 'o' and then it always crashes within a second. Here's the message: {{{ hdur: internal error: Invalid object in isRetainer(): 8 (GHC version 7.10.3 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8406#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
