Hi

I am using the ghcjs 8.10 via Haskell.nix, and hit this issue when using reflex-dom package.

lib.js:1868 Uncaught ReferenceError: h$ghcjszmprimZCGHCJSziPrimziJSVal_con_e is not defined
    at lib.js:1868
rts.js:7280 uncaught exception in Haskell main thread: TypeError: Cannot read property '1' of undefined
rts.js:7280 TypeError: Cannot read property '1' of undefined
    at h$base_isatty (lib.js:3861)
    at h$$jQ (out.js:13998)
    at h$runThreadSlice (rts.js:8456)
    at h$runThreadSliceCatch (rts.js:8421)

    at rts.js:2518
    at runIfPresent (rts.js:2537)
    at onGlobalMessage (rts.js:2585)

This seems to be caused by the following commit

commit e4cd4232a31f6371c761acd93853702f4c7ca74c (HEAD -> ghc-8.10, moto/hkm/nix-ghc-8.10, moto/ghc-8.10)

    Remove additional JSVal constructor initializer. apparently this was
    used for debugging only, but it causes tools to complain about
    duplicate declarations.

    Multi-file index.html (rts.js, out.js, lib.js, runmain.js) appears
    to run fine with this removed.

I confirmed at my end that the e4cd423 indeed is the cause behind the error.

Ran into the same issue today, but was able to fix it (for my project at least) by using an single-file index.html, e.g.

<!DOCTYPE html>
<html>

<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>JSaddle</title>
  <script src="all.js"></script>
</head>

<body>
</body>

</html>
