The bad commit seems to be:

    commit 62efc4ba3eb53ca75abbe9b52feabe49a5fd56b5
    Author: Aapo Tahkola <aet@rasterburn.org>
    Date:   Thu Jan 18 05:56:13 2007 +0200

        support as much of GL_EXT_stencil_two_side as we can. untested.




I will forward this bug upstream tonight (unless you're already doing it
