Creating a DataFrame from Series with unsorted indeces gives completely bad data

Creating a DataFrame from Series with unsorted indeces gives completely bad data.

I've written a module that reproduces the bug—unless this is by design. Give it a try.

(I'm running pandas==0.8.1, Python 2.7.2, and OS X Mountain Lion.)

It turns out it's by design—

While pandas does not force you to have a sorted date index, some of these methods may have unexpected or incorrect behavior if the dates are unsorted. So please be careful

No, what you show in the script looks like a bug, let me have a look.

Definitely a bug. I'll sort out a fix right now once I figure out what's happening

Fixed the underlying issue
