Comment (by darchon):

 I've managed to reduce the test case a bit, relying only on the unbound-
 generics package (and its transitive dependencies):

 * git clone https://github.com/christiaanb/IfaceError.git
 * cd IfaceError
 * stack build

 I will try to reduce it further to get rid of the unbound-generics
 dependency.
