#8717: Segfault in 64-bit Windows GHCi -------------------------------+---------------------------------------- Reporter: awson | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: GHCi | Version: 7.8.1-rc1 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: GHCi crash | Difficulty: Difficult (2-5 days) Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------+---------------------------------------- Comment (by awson): Phew. That was a nightmarish debugging experience. At last, I've found that some code in {{{base}}} wants to access {{{GetCommandLineW}}} not at an exact trampolined address but with {{{+1}}} offset. I am extremely tired, so I've decided to not dig further in {{{GHCi}}} with {{{base}}} interaction and simply exposed {{{GetCommandLineW}}} to {{{GHCi}}} statically. Thus, {{{GetCommandLineW}}} is loaded by a system linker and is not trampolined anymore. This is ugly hack, but it works and makes {{{GHC}}} build, for example, {{{llvm-general}}} package - impossible thing before. This patch applies to 7.8 and HEAD. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8717#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
