I still experience this panic on GHC 7.8.2 with Windows x86_64:

But not with GHC 7.8.2 on Linux x86_64:

This has caused problems for me when running programs such as [https://github.com/ku-fpg/hermit/ HERMIT] on Windows, since at some
Hello,
A similar panic also happens when running Liquid Haskell [http://goto.ucsd.edu/~rjhala/liquid/haskell/blog/about/] on a file that uses the Units of Measure plugin [https://github.com/adamgundry/uom-

A workaround is to call {{{initStaticOpts}}} manually somewhere in the program, but I feel like that shouldn't be necessary. The one above was on Windows. Also reported: plugin]
