 Replying to [comment:5 mpickering]:

 Maybe try deleting the local .stack-work directory as well? I don't know
 where stack puts interface files by default.

 I did, but this did not produce any change whatsoever. Any other idea as
 to what may be causing this issue? I do not have ghc installed globally,
 only through stack, so there (shouldn't) be interference between the
 different ghc versions that stack has.
