This page is intended to serve as repository for one or more small, community-edited examples of Haskell programs which actually leak space with state-of-the-art tools. That means it should preferably leak even when compiled with the latest GHC -O2, but certainly should leak with default -O. This is the one thing that the many excellent wiki and blog pages about space leak don't deliver. It's frustrating to study about leak when the examples given no longer leak for us! :)
Maybe this page should be moved to just Leak and then we can present others (eg. time leak) as well?
For general text about space leak, please see memory leak.
I haven't had a chance to mark up this page yet, but the intended initial content is available at the leaky project homepage.
