177 unexpected test failures on a new system -- is this yet another linker issue?

Fri Nov 11 21:26:18 UTC 2016

Sylvain, I tried your patch, here's the output:

    cd "./th/T5976.run" &&  "/home/omer/haskell/ghc/inplace/test
spaces/ghc-stage2" -c T5976.hs -dcore-lint -dcmm-lint
-no-user-package-db -rtsopts -fno-warn-missed-specialisations
-fshow-warning-groups -dno-debug-output -XTemplateHaskell -package
template-haskell -fexternal-interpreter -v0
    Actual stderr output differs from expected:
