Bug #18941: Endless loop with a memory leak in FileUtils::mkpath
https://bugs.ruby-lang.org/issues/18941

* Author: inversion (Yura Babak)
* Status: Open
* Priority: Normal
* ruby -v: 3.1.2p20 (2022-04-12 revision 4491bb740a) [x64-mingw-ucrt]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
On Windows 10 with Ruby `3.1.2p20 (2022-04-12 revision 4491bb740a) [x64-mingw-ucrt]`,
an attempt to create a path on the offline external drive stuck with a memory leak:
``` ruby
require 'fileutils'
FileUtils.mkpath 'W:/new_dir'
```
Same code with `Ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x64-mingw32]`
throws an error as expected:
```
fileutils.rb:253:in `mkdir': No such file or directory @ dir_s_mkdir - W:/new_dir (Errno::ENOENT)
```
