There appears to be a bug with regards to SwapStrategy.stable. If you don't
pass
it a swap strategy it works just fine, but if you do, it fails.
I'm using svn snapshot 1751 of phobos, which is a few weeks old, and it fails
an
assertion in sort() which is checking whether the range was sorted. I have no
idea if it's been fixed since then. I don't see a bug report for it in either
case.
