No, you need 2.3.10 or newer.
However, I've identified the problem but it's hard to fix quickly. It is deeply rooted in the used drop-out algorithm (or rather, the improvements I've added), and good rendering of the test case provided by Ian needs an additional constraint.
As soon as time permits I'll post a complete description of the problem on the freetype-devel mailing list.
