#10761: GHC panic when compiling vimus: failed to map segment from shared object -------------------------------------+------------------------------------- Reporter: haasn | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Linux Architecture: x86_64 | Type of failure: Compile-time (amd64) | crash Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- When trying to build https://github.com/vimus/vimus I get a GHC panic on a specific module: {{{ λ cabal build Building vimus-0.2.1... Preprocessing library vimus-0.2.1... [38 of 39] Compiling Vimus.Command ( src/Vimus/Command.hs, dist/build/Vimus/Command.o ) ghc: panic! (the 'impossible' happened) (GHC version 7.10.2 for x86_64-unknown-linux): Loading temp shared object failed: /tmp/ghc17990_0/libghc_39.so: failed to map segment from shared object Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug }}} I don't know why it's only this particular module of this particular library that fails. I'm running a kernel with GrSecurity and PaX enabled, and am using a hardened GCC toolchain (although Gentoo seems to automatically disable PIE for Haskell packages). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10761 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
