GCC 4.5 Lambdas

I just found out the lambda branch was merged into 4.5 and I was wondering if anyone has tried them yet? Is it just a merge or did they fix the bugs? Specifically, the "internal compiler error" when passing a lambda a variable dependent on a template (any templated class couldn't use "this" with lambdas).

I would check but I've been OS hopping and I'm on Windows, and it took me a while to get it working in the first place (not Linux savy).

Thanks in advance!

Edit: They did fix it (woot!), unfortunately introducing a couple new bugs.
