#7134: ghc-7.6.0.20120810-x86_64-windows.exe -> internal error R_X86_64_PC32 -------------------------------+---------------------------------- Reporter: cetinsert | Owner: thoughtpolice Type: bug | Status: patch Priority: highest | Milestone: 7.8.1 Component: GHCi | Version: 7.6.1-rc1 Resolution: | Keywords: R_X86_64_PC32 Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: GHCi crash | Difficulty: Unknown Test Case: | Blocked By: 3658 Blocking: | Related Tickets: -------------------------------+---------------------------------- Comment (by awson): I've updated the patch for HEAD. Now: 1. Memory for trampolines is reserved right next to memory for image. We reserve this space for all symbols in image. This could look as overkill, but this is the way it is done in unixish cases, and also {{{VirtualAlloc}}} takes physical memory from system lazily (only when relevant page is accessed), and we don't need to save virtual space because we have plenty of it. Unlike in unixish cases, though, we avoid any reallocations because we can take the number of symbols from PECoff header. 2. Loading of archives is fixed. Looking into the code I can say it never worked for static GHCi linker on Win64. Now it works. Don't try to remove prelinked HSbase-4.7.0.0.o though :) otherwise ghci segfaults trying to set buffering status for base's stdin, stdout and stderr. I suspect, this is related to the way {{{initInterpBuffering}}} in {{{GhciMonad.hs}}} works. 3. Disabled {{{.ctor}}} handling comments now contain the number of related ticket, which I've created for this. 4. The status is documented in release notes. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7134#comment:47 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
