#16130: GHC Panic on OS X: Data.Binary.Get.runGet: Invalid magic number "INPUT(-l" ----------------------------------------+--------------------------------- Reporter: basvandijk | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Keywords: | Operating System: MacOS X Architecture: Unknown/Multiple | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ----------------------------------------+--------------------------------- When building the latest `opencv-extra` library on OS X I'm getting a GHC panic. To reproduce git clone https://github.com/LumiGuide/haskell-opencv, make sure Nix is installed and execute: {{{
nix-build -A haskellPackages.opencv-extra ... [11 of 11] Compiling OpenCV.Extra ( src/OpenCV/Extra.hs, dist/build/OpenCV/Extra.p_o ) ghc: panic! (the 'impossible' happened) (GHC version 8.6.3 for x86_64-apple-darwin): Data.Binary.Get.runGet at position 8: Invalid magic number "INPUT(-l" CallStack (from HasCallStack): error, called at libraries/binary/src/Data/Binary/Get.hs:351:5 in binary-0.8.6.0:Data.Binary.Get }}}
The library builds successfully on Linux. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16130 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
