Comment (by prsteele):

 I have attached a ZIP file containing a snapshot of the project. The
 project currently can be compiled via `cabal build create-tables`.
 However, if you remove the `-fsimpl-tick-factor=131` in the
 `recipes.cabal` file (or decrease the number to 130 or below) the bug
 appears.
