I get this when I run the unit tests now:
======================================================================
FAIL: Test evaluate basis agains FIAT.FiniteElement.tabulate().
----------------------------------------------------------------------
Traceback (most recent call last):
File
"/home/logg/work/src/fenics/ffc/ffc-main/test/unit/evaluate_basis/test.py",
line 20, in testAgainsFiat
self.assertEqual(error, 0, "Errors while testing evaluate_basis
against FIAT, see fiat_errors.log for details")
AssertionError: Errors while testing evaluate_basis against FIAT, see
fiat_errors.log for details
And things like this in error.log:
-------------------------------------------------------------------------------

So the tolerance might need to be increased. Something like 1e-8
should be ok.
I also get this:
*** FFC: Sorry, finite element of type "Brezzi-Douglas-Fortin-Marini"
are not supported by FIAT.
*** FFC: To get more information about this error, rerun FFC with
--debug.
I didn't think BDFM was supported by the new FIAT.
