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.

Is it when I install dolfin? I usually use dorsal, where shall change in this case?

Hi,

I am trying to use
valgrind --tool=cachegrind ./demo

to check the performance of my code, but I get the following error:

==27082==
terminate called after throwing an instance of 'CGAL::Assertion_exception'
   what():  CGAL ERROR: assertion violation!
Expr: -CGAL_IA_MUL(-1.1, 10.1) != CGAL_IA_MUL(1.1, 10.1)

Have anyone tried it out?
