Use of template-haskell is broken with shared libraries

Consider the following program:

TH.hs:

{-# LANGUAGE TemplateHaskell #-}
module TH where

import Language.Haskell.TH

spliceMe = [| (\xs -> tail xs ++ init xs) |]

Library.hs

{-# LANGUAGE TemplateHaskell #-}
module Library where

import TH

main = print ($(spliceMe) [1, 2])

Build it like so:

ghc --make -package-name foo-0.2.3 -hide-all-packages -fbuilding-cabal-package -no-user-package-conf -i -idist/build -i. -idist/build/autogen -Idist/build/a
utogen -Idist/build -optP-include -optPdist/build/autogen/cabal_macros.h -odir dist/build -hidir dist/build -stubdir dist/build -package-id base-4.2.0.0-e0460a0a4effe0aca049da0e
12eab4d3 -package-id template-haskell-2.4.0.0-fa9ea4aecb54a2910620fe9afd9f40f1 -O Library -dynamic -hisuf dyn_hi -osuf dyn_o -fPIC

And observe the wonderful error:
