After running `test_config` it takes a few seconds for the panic to occur.
If I compile the first five files, the panic seems to disappear, so my
guess it is some problem with interpreted code:
{{{
$ ghc --make -package ghc Scion.Types
...
$ ghci -package ghc Scion/Config.hs
*Scion.Config> test_config
-- no segfault
*Scion.Config> :q
Leaving GHCi.

I attached the source files. You'll need additional packages, though.
See the full output above for which ones these are.
