GSOD when installing ghc-mod

[n3dst4]

• Your Windows build number:
  ~Microsoft Windows [Version 10.0.17063.1000]~ ~Microsoft Windows [Version 10.0.17074.1000]~ Microsoft Windows [Version 10.0.17074.1002]

• What you're doing and what's happening:

I'm trying to install and run the Haskell IDE-integration tool ghc-mod, using the Haskell build tool "stack".

1. Open Ubuntu 16.04 from Microsoft Store
2. Run

   sudo apt-get update
   sudo apt-get upgrade

3. Install stack, the Haskell build tool, by running

   wget -qO- https://get.haskellstack.org/ | sh

4. Create a dummy project and build it

   stack new foo simple --resolver=lts-9.3
   cd foo
   stack setup # this will take a long time, like 20 mins
   stack build

5. If all has worked so far, make sure you've saved your work and closed any other windows, and then run:

   stack build ghc-mod

• What's wrong / what should be happening instead:

Windows crashes (green screen of death). I have replicated this on two machines.

• Strace of the failing command, if applicable: (If some_command is failing, then run strace -o some_command.strace -f some_command some_args, and link the contents of some_command.strace in a gist here)

@n3dst4 - Thanks for the detailed repro steps. I have a local repro. We will be submitting a fix for this soon.

[n3dst4]

Just to confirm, this crash is still present in 17074 (I wasn't expecting a fix yet, just updating the build number.)

@benhillis and @sunilmut Thank you. I just tried this on 17083 and it works great 👍
