I inserted the following stack.yaml into ghcjs-base and executed stack ghci in ghcjs-base.

resolver: lts-6.20
compiler: ghcjs-0.2.0.9006020_ghc-7.10.3
compiler-check: match-exact

setup-info:
  ghcjs:
    source:
      ghcjs-0.2.0.9006020_ghc-7.10.3:
        url: http://ghcjs.tolysz.org/lts-6.20-9006020.tar.gz
        sha1: a6cea90cd8121eee3afb201183c6e9bd6bacd94a

packages:
- '.'

extra-deps: []

flags: {}

extra-package-dbs: []

I had to push through multiple instances of segmentation faults to launch REPL on ghcjs-base. Does this issue still exist?

stack ghci works fine on small toy GHCJS projects. Thus, I conjecture that it is related to nodejs memory limitations.

I found a good way to debug this issue.
I just needed to compile ghcjs with --profile or --enable-profiling.
+RTS -xc -RTS will reveal the stack trace.

I can't compile stack and ghcjs-ghc7 with profiling.

ghcjs-ghc8 will probably be ok with profiling.

For stack, refer to commercialhaskell/stack#2751
