 In a freshly cloned GHC code base (c6462ab0...), in my system,`make test
 TEST="T13780c T13822"` fails.That is while `./validate` passes.

 Specifically, I follow the following steps:
 (1) `git clone --recursive git://git.haskell.org/ghc.git`
 (2) `cd ghc`
 (3) `cp mk/build.mk.sample mk/build.mk`
 (4) set `BuildFlavour = devel2` and then
 (5) ./boot
 (6) ./configure
 (7) make -j4
 (8) make test TEST="T13780c T13822"

 I build in a variant of the docker image for GHC development on Linux (64
 bit), if it matters.

 As it seems, @alanz also gets the similar result on his system.
