GHC panic when using GHC plugins

I'm running GHC 8.0.2 on Windows 10. At first I was playing around with making my own type-checker plugin and I kept getting

ghc.EXE: panic! (the 'impossible' happened)            
  (GHC version 8.0.2 for x86_64-unknown-mingw32):      
        Static flags have not been initialised!        
        Please call GHC.parseStaticFlags early enough. 

on certain function calls (things like printing Docs). But now on an unrelated project I tried using the dump-core plugin and I'm getting the same error.

The minimal example I can produce is simply

module Main where
main = return ()

compiled with

stack exec ghc -- -fplugin=DumpCore PluginTest.hs (or I'm guessing equivalently ghc -fplugin=DumpCore PluginTest.hs)

Make sure to install the dump-core package first.
