New description:

 I've attached a no-Haskell-code project that fails when I run `cabal repl`
 with the following error:


 {{{
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.10.3 for x86_64-unknown-linux):
         Loading temp shared object failed: /tmp/ghc60744_0/libghc_1.so:
 undefined symbol: _ZN2Zq1qE
 }}}

 Building the project works fine, so the problem seems to be (only) with
 dynamic linking. The issue can be resolved by swapping the order of the
 .cpp files in the cabal file.
