I get occasionally get a CGAL error when running DOLFIN:

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)
File: /home/garth/local/include/CGAL/Interval_nt.h
Line: 158
Explanation: Wrong rounding: did you forget the -frounding-math option
if you use GCC?
==10917==

It typically arises when trying to run inside a debugger, etc. Has
anyone else seen this? I do compile with '-frounding-math'.
