Is there anybody with cmake/ctest experience who knows how to set up 
(automatically) running the tests with valgrind?

I found some further occurrences of that construct and decided to use 
your suggestion, I also improved your unit test slightly and added the 
possibility to run the unit-tests with exceptions disabled:

https://bitbucket.org/eigen/eigen/commits/c071cfb

I locally ran the unit-tests before pushing, but only on g++4.8 and 
clang3.4 (both with and without exceptions). It would be nice if someone 
could check MSVC as well.
