Comment:

 It works for me as well, using GHC 8.0.1 and
 http://www.stackage.org/snapshot/nightly-2016-06-02, which contains cereal
 0.5.2.0.

 This seems to have fixed it, from the cereal 0.5.2.0 release notes:
 > Split the GSerialize class in two, to deal with a GHC bug (thanks Austin
 Seipp!)

 The GHC bug they refer to is #5642, and it is still open.

 Thanks again for reporting.
