Flow: on Windows: Unhandled exception: Sys_error("Invalid argument")

[amcsi]

Whe running flow server with Flow 0.35.0 on Windows: when detecting a change in a file, there's a high random chance that I see this outputted:

[2017-01-30 20:20:03] Merge prep

Unhandled exception: Sys_error("Invalid argument")

Then the application terminates.

I have similar issue. I use flow 0.37.4 with Webstorm.
Often see in log
Error: Sys_error("Invalid argument")
Most of time it go in pair with

If I run ./node_modules/.bin/flow in a console, Flow seems to execute fine.

Have same issue. Moreover standard-flow doesnt work in my projetc althoug I wrote it in extends rule

[AndrewMorsillo]

Here is the issue on Jetbrains issue tracker I am not sure if the error is with Flow or with Jetbrains products as flow seems to work fine with VS Code and Nuclide on windows.

[rastogitech]

Same issue on Webstorm 2017.2.5 and flow 0.53.0.
