Well, some swap functions in ublas/storage.hpp take their arguments by value, and MSVC2010 (took me forever to install MSVC2010beta2, my machine rebooted 3 times) is lucky enough to find those broken swap functions, but miss the better and faster iter_swap function.

I created a patch (see attachment) and a ticket for this (I can't imagine how a swap function taking its arguments by value could possibly work correctly, but I guess it's just missing imagination):
