Bug #1911: Memory leak in Dir.glob on Windows
http://redmine.ruby-lang.org/issues/show/1911

Author: Heesob Park
Status: Open, Priority: Normal
Category: core, Target version: 1.9.x
ruby -v: ruby 1.9.2dev (2009-08-08 trunk 24444) [i386-mswin32_90]

I found the memory leak in Dir.glob of Ruby 1.9 (trunk) on Windows.

After running this code

ruby -e 'for i in 0..100000;Dir.glob("c:/*");end'

The memory usage is increasing steeply and never decrease.

I guess that leak is due to the several WCHAR pointers in win32.c. I noticed that pointer is allocated for MultiByteToWideChar function and not freed afterward.
