No. We could try using std::nth_element from Boost, but I think the
interface is different and it's generating work for us when it
should be fixed elsewhere. I've created an Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/gcc-4.8/+bug/1246802
It was relatively easy to switch to the boost interface once I looked
closer at it so I will push a change which uses
boost::nth_element in place of std::nth_element.
Great. Leave plenty of comments so we can switch back again once the bug
is fixed in Ubuntu (or much more likely, Ubuntu 14.04 arrives since
Ubuntu doesn't seem to fix bugs).

Before I push the fix I want to run the benchmarks and see that it
doesn't degrade the performance. (Will check later tonight.)

I don't know. I thought maint should come off a released version?
Maybe it should be a named branch, e.g. 1.3rc?

It looks better than I remembered. DOLFIN, FFC, Instant are in sync
at v1.2, but FIAT, Ferari and UFC are out of step.
On a side note, I couldn't find a link to tarballs of the releases
from the web page.
