ghc panic: -fexternal-interpreter + .o + QuasiQuotes?

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

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

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

1. 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):

Loading temp shared object failed: /home/blynn/.local/lib/ghc-8.0.2/ghc-prim-0.5.0.0/libHSghc-prim-0.5.0.0-ghc8.0.2.so: undefined symbol: stg_thawArrayzh

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
