uncaught exception in Haskell thread: Error: invalid big integer: incorrect number of limbs

[RobertFischer]

Getting a bunch of these issues using this build:

resolver: lts-9.21
compiler: ghcjs-0.2.1.9009021_ghc-8.0.2
compiler-check: match-exact
setup-info:

        sha1: b1740c3c99e5039ac306702894cd6e58283f4d31

Here is what the errors look like:

Any tips on what's going on and how to work around it?

Can you provide some info about your environment? Windows/Linux etc?

[RobertFischer]

Let me know if anything else is helpful.

Looks like it was an issue with the bytestring shim: https://github.com/ghcjs/ghcjs/issues/662 Do we need to do anything to get this shim into ghcjs-0.2.1.9009021_ghc-8.0.2?

[matchwood]

Ah good work. I was only asking for the distro in case it was a Windows issue.

We do indeed need to do something - I need to rebuild the stack release against the new shim. I'll try to get this done in the next day or two (you are also welcome to do it! I can give pointers if you like).

[RobertFischer]

Can I throw you some cash to make this happen faster? I kinda need it ASAP.

[matchwood]

Haha I will try to do it now.
