Bug #10973: Silent failure when launching ruby with command line parameters for script that matches directory and contains [
https://bugs.ruby-lang.org/issues/10973

* Author: Thomas Sondergaard
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.1p85 (2015-02-26 revision 49769) [x64-mingw32]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
I have a script that passes a regular expression to a ruby script that matches a file path. This regular expression contains the character '['. After upgrading from ruby 2.0.0 to ruby 2.2.1 on Windows ruby no longer works when a script is passed a command line argument that partially matches a directory and contains the character '['. See the following example:

First example: Current working dir is D:\ and 'D:\foo' doesn't exist. The script executes without incident:
d:\>ruby -e "puts 'hello'" D:/foo/bar/[
hello
d:\>echo %errorlevel%
0

Second example: Same current working directory and same command, only now there is a directory D:\foo:
d:\>mkdir foo
d:\>ruby -e "puts 'hello'" D:/foo/bar/[
d:\>echo %errorlevel%

This is a regression from earlier version of ruby. I have not tested on other platforms than Windows.
