 1. Compile an object file with -fPIC, e.g:

 {{{
 cat > hello.c << EOF
 #include <stdio.h>
 void hi(){puts("Hello, World!");}
 EOF
 gcc -c -fPIC hello.c
 }}}

 2. Write Haskell that uses QuasiQuotes, e.g:

 {{{
 cat > h.hs << EOF
 {-# LANGUAGE QuasiQuotes #-}
 import Text.Heredoc (here)
 s :: String
 s = [here|goes nothing|]
 EOF
 }}}

 3. Compile with -fexternal-interpreter:

 {{{
 cabal install heredoc
 ghc -fexternal-interpreter h.hs hello.o
 }}}

 I saw:

 [1 of 1] Compiling Main             ( h.hs, h.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 8.0.2 for x86_64-unknown-linux):
