Fantomas hangs indefinitely when run

[willd-mwp]

Description

After installing fantomas-tool, when running fantomas against a file or folder, the process hangs indefinitely, with no output being produced, the process needs to be given a force quit ctrl-c to return back to the terminal.

Repro code

I have tried with both the stable channel and the preview release of fantomas-tool. I cloned the repo to try some further debugging. Running build.sh was successful, with all tests passing. After building, if I then run the built fantomas-tool.dll directly against a file, fantomas seems to operate correctly, and produces a formatted F# source file.

Windows 10
.NET Frameworks 4.6.1 (and later) SDKs and targeting packs are installed.
.NET Core 2.1 and 2.2 are installed.

Did you built from the master branch or the trivia?

Could you try the trivia branch? If you there encounter a problem that you can share with us, we can act upon it. Otherwise I don't really see the call to action here.

While experimenting with this, I tried running fantomas from different terminals, I had been running it through git bash before, it seems to work fine via cmd and powershell, so I guess it's not playing happy with git bash for some reason...

Interesting.

Can reproduce (in trivia branch) in git bash and cygwin. However in WLS bash it works fine. Looks like some problem with mingw/cygwin.

Don't know if it is even possible to debug this, and if it is that important issue.

Yeah I wouldn't know where to start with debugging this, and whether the problem is within the scope of this repo at all, but I thought it would be useful to document what I had discovered, in case anyone else encounters this and starts googling, because I couldn't find any mention of it elsewhere.

I'm going to close this as it doesn't sound actionable to me.
