Problems with bashcov on bash for Windows

[ale5000-git]

I run it like this (bashcov 3.1.2 on Windows 10):

bash
BASHCOV_BASH_PATH='bash' bashcov -- ./my_script.sh

and I get:

bashcov: warning: running as root is NOT recommended, Bashcov may not work properly.
C:/Ruby-x64/lib/ruby/gems/3.0.0/gems/bashcov-3.1.2/lib/bashcov/runner.rb:59:in `spawn': wrong file descriptor (4) (ArgumentError)

1. It isn't root, the detection doesn't work.
2. If I comment the line 34 options[fd] = fd # bind FDs to the child process, then the script go on (obviously without this line doesn't work correctly).
