I can reproduce the issue on my end with 7.6.3.  Setting
-fsimpl-tick-factor=10000 allows the build to proceed. This is a bit odd
as I don't see anything in your code that should give the simplifier too
much grief, but I could be missing something.  Unless you intend on
releasing the code I would probably add a 'Ghc-Options:
-fsimpl-tick-factor=1000' to your Cabal file for now.
