Subject: [ruby-core:40904] [ruby-trunk - Bug #5591] Windows bug when using "shortcut" syntax with output redirection


Issue #5591 has been updated by Heesob Park.


I can reproduce this issue with trunk on Windows XP.

The changeset r33692 solves this bug too.

On Windows XP, fstat failed with errno EACCES when called with shortcut and redirected stdout.

  $

Expected `test > out' to behave like `ruby test.rb > out'.

Bug occurs with both 1.9.3 (RubyInstaller) and 1.9.2 (Binary); 1.8.7 (RubyInstaller) behaves as expected. Tested on Windows XP Version 2002 Service Pack 3; originally reported on Windows 7.
