 Repro steps:

 * `git clone https://github.com/purescript/purescript`
 * `cd purescript`
 * `git checkout v0.11.2`
 * `stack build --profile`

 The error was:

 Sorry that this is pretty much the complete opposite of a minimal
 reproducing example, but I have no clue how to go about isolating the part
 that's actually causing the problem.
