Panic when shared object file is missing: Dynamic linker not initialised

    • Closed Issue created by Ryan Scott @RyanGlScott

    There are several Trac tickets floating around which mention this panic, including:

    • #9868 (closed) (ghc: panic! Dynamic linker not initialised)
    • #10355 (closed) (Dynamic linker not initialised)
    • #10919 (closed) (ghc: panic! (the 'impossible' happened) ... Dynamic linker not initialised)
    • #13137 (closed) (Dynamic linker not initialised.)
    • #13531 (closed) (GHC fails with "Dynamic linker not initialised" when -j is on and trying to load nonexistent .so file)

    However, none seem particularly simple to reproduce. I have a (marginally) easier way to trigger this panic. You'll need the following:

    • A copy of GHC HEAD built with the prof flavor. For reference, I am using GHC HEAD built against 1f4fd37e.
    • A single package built with cabal-install. For simplicity, I used random:
    $ cabal install random-1.1 -w ~/Software/ghc3/inplace/bin/ghc-stage2

    Once it's installed, you'll need to learn random's package ID, which can be done with ghc-pkg. For instance:

    3$ ~/Software/ghc3/inplace/bin/ghc-pkg describe random
name: random
version: 1.1
id: random-1.1-Gnn89iTXDuaz90MEyLmyr
...
    • You'll need these three Haskell files:
    -- Foo.hs
{-# LANGUAGE TemplateHaskell #-}
module Foo where

import Language.Haskell.TH

foo :: Bool
foo = $(conE 'True)
    -- Foo2.hs
{-# LANGUAGE TemplateHaskell #-}
module Foo2 where

import Language.Haskell.TH

foo2 = $(conE 'False)
    -- Bar.hs
module Bar where

import Foo
import Foo2

bar :: ()
bar = foo `seq` foo2 `seq` ()

    Once you have all of these, you can trigger the bug by invoking GHC like so:

    $ ~/Software/ghc3/inplace/bin/ghc-stage2 -fforce-recomp Bar.hs -j2 -package-id random-1.1-Gnn89iTXDuaz90MEyLmyr

      Actually, you don't need a profiled compiler after all. You can reproduce this with an ordinary GHC with one extra step.

      As before, install some library, like random-1.1:

      $ cabal install random-1.1 -w /opt/ghc/head/bin/ghc

      Then figure out its package ID:

      $ /opt/ghc/head/bin/ghc-pkg describe random
name: random
version: 1.1
id: random-1.1-Gnn89iTXDuaz90MEyLmyr
...

      This time, however, you'll need to change the contents of .cabal (where cabal-install puts its shared object files). On Linux, this can be accomplished like so:

      $ cd ~/.cabal/lib/x86_64-linux-ghc-8.3.20170509/
$ mv libHSrandom-1.1-Gnn89iTXDuaz90MEyLmyr-ghc8.3.20170509.so libHSrandom-1.1-Gnn89iTXDuaz90MEyLmyr-ghc8.3.20170509-dummy.so

      Now compile Bar.hs as before:

      $ /opt/ghc/head/bin/ghc -fforce-recomp Bar.hs -j2 -package-id random-1.1-Gnn89iTXDuaz90MEyLmyr

      From this I think we can assume that initializing the linker just failed. We put the panic back into the MVar and when the other thread got to read it we failed hard.
