Question #127201 on DOLFIN changed:
https://answers.launchpad.net/dolfin/+question/127201

    Status: Open => Answered

Anders Logg proposed the following answer:
You need to set this option to run with Valgrind:

  CGAL_DISABLE_ROUNDING_MATH_CHECK

This will configure the build against CGAL so that CGAL does not
interfere with Valgrind. If you use cmake-gui, you should be able to
see this option and just click it.
