#8935: Obscure linker bug leads to crash in GHCi -------------------------------------+------------------------------------ Reporter: simonmar | Owner: simonmar Type: bug | Status: patch Priority: high | Milestone: 7.8.3 Component: Runtime System | Version: 7.8.1-rc2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: GHCi crash | Difficulty: Rocket Science Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Changes (by trommler): * owner: trommler => simonmar Comment: The attached patches change the way shared libraries are loaded (dlopen) by the runtime system and the way temporary shared libraries are linked for files compiled to object code in GHCi. The first patch [https://ghc.haskell.org/trac/ghc/attachment/ticket/8935/0001-Fix-GHCi- crash-on-access-to-process-environment.patch] implements the changes for Linux and I validated those on x86_64 (openSUSE 13.1). The second patch [https://ghc.haskell.org/trac/ghc/attachment/ticket/8935/0001-Fix-GHCi- linking-of-files-compiled-to-object-code.patch] might be needed for OS X. This patch is not validated as I do not have access to an OS X machine at the moment. Simon, please have a look at the patches and the commit messages and let me know what could be improved. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8935#comment:51 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
