Continuing the discussion from here.

Running on a Windows 7 64bit, I get the following when running stack ide start on a project:

The source of the exception is this line in ValueStream.hs.

I found a similar issue on the bytestring issue tracker. I submitted a minimal example, that doesn't depend on stack-ide, that fails in the same way (see here).

I wonder what the differences are in our environment — I'm running under MSYS2 using Cmder on Windows 8 x64.

I'm using Cmder as well, but I'm on a Windows 7 x64. Though I see the same error when I use plain cmd.

Even more strangely, the error goes away when using WinGhci
