GHCi panics, though project builds just fine.
Summary
For the haskell-cpython project, attempting to launch GHCi causes a panic, although I can build the project without issue.
Steps to reproduce
- Clone the GitHub repository above.
- Move into the top level directory of the newly cloned repository.
- Execute:
stack setup
. - Execute:
stack build
. (Note that it succeeds.) - Execute:
stack ghci
. (Observe the panic.)
Expected behavior
I expect it to cause a GHC panic.
I want it to launch a GHCi session w/ my packages imported and ready to go.
Environment
- GHC version used: 8.4.4 (Stack resolver LTS-12.18)
Optional:
- Operating System: MacOS X 10.14.5 (Mojave)
- System Architecture: MacBook Pro (<1yr. old; 32 GBytes RAM)
