#8376: Static Executable + GHC API (+ Dynamic Linking?) gives Segfault ----------------------------------+---------------------------------- Reporter: darchon | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ----------------------------------+---------------------------------- Comment (by darchon): On Linux (GHC-b84fbabb0cad88a5b1ae62a53e04075383bc11f4), using a statically-linked `haddock`, I get: {{{ ~/devel/lens/src (master *)$ haddock -v3 Control/Lens/Internal/ByteString.hs Creating interfaces... Haddock coverage: Checking module Control.Lens.Internal.Level... Creating interface... 100% ( 6 / 6) in 'Control.Lens.Internal.Level' <MORE LOG MESSAGES> 100% ( 6 / 6) in 'Control.Lens.Internal.Getter' Checking module Control.Lens.Internal.Fold... <command line>: can't load .so/.DLL for: /home/baaijcpr/multi- ghc/7.7.20131002/lib/ghc-7.7.20131002/ghc-prim-0.3.1.0/libHSghc- prim-0.3.1.0-ghc7.7.20131002.so (/home/baaijcpr/multi- ghc/7.7.20131002/lib/ghc-7.7.20131002/ghc-prim-0.3.1.0/libHSghc- prim-0.3.1.0-ghc7.7.20131002.so: undefined symbol: stg_forkOnzh) }}} Also on Linux, the dynamically-linked `haddock` runs _without_ failure. I also want to note that `Control.Lens.Internal.Fold` is one of the source-files in the `lens` package that contains a `{-# ANN ... #-}` annotation. Removing the annotation makes the statically-linked haddock go through until another file with a `{-# ANN ... #-}` annotation is found, and subsequently stops with the same failure. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8376#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
