Comment (by albertov):

 I've created a [https://github.com/meteogrid/sigym4-geometry/tree/ghc-9971
 new branch] in my library to track this down from the first revision that
 causes the problem (2b00e8f5052cc392). I've removed the `-O2` flag from
 the `test` section of the .cabal file (the library section didn't have it)
 and configured with: `cabal configure --disable-optimization --ghc-
 options="-v3" --enable-tests -w /usr/local/bin/ghc-7.10.0.20141222`.  The
 output of the configure step is:

 The executed `cabal build > build.log 2>&1`and waited for the OS to kill
 ghc. I've attached the resulting build.log file.
