##To reproduce
Clone, then run stack build.
The build will work if you remove the llvm-general dependancy in bug-test.cabal, or if you comment out the line foo in Lib.hs

| # Resolver to choose a 'specific' stackage snapshot or a compiler version. | |
| # A snapshot resolver dictates the compiler version and the set of packages | |
| # to be used for project dependencies. For example: | |
| # | |
| # resolver: lts-3.5 | |
| # resolver: nightly-2015-09-21 | |
| # resolver: ghc-7.10.2 | |
