Bug #1482: Kernel.exec doesn't respect COMSPEC environment variable on Windows
http://redmine.ruby-lang.org/issues/show/1482

Author: Evgeniy Dolzhenko
Status: Open, Priority: Normal
Category: core, Target version: Ruby 1.8.7
ruby -v: ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-mswin32]

Here is pretty convoluted test case:

puts ENV["COMSPEC"] # => "C:\WINDOWS\system32\mycmd.exe"

File.open("1.bat", "w") { |f| f.write("time") } # create test batch file with command which waits for user input

Kernel.exec("1.bat") # now the process tree inspection shows that the "C:\WINDOWS\system32\cmd.exe" is still used to interpret 1.bat
