gnu/packages/patches/ghc-microlens-aeson-fix-tests.patch

   1 This patch fixes the test suite to allow any order when listing the
   2 members of a JSON object.  Aeson (being true to the JSON specification)
   3 does not specify an order for objects.  In practice, the order depends
   4 on your processor architecture.

   7 in a similar patch fixing the Aeson tests.
