CGAL users discussion list

["Sebastien Loriot (GeometryFactory)" <>]

There used to be a page giving patches to handle rounding mode in
valgrind here:
csa.inf.ethz.ch/valgrind

but the page seems no longer accessible.

Maybe you should try:

http://code.google.com/p/address-sanitizer/

Note that it is a built-in with gcc 4.8 and clang 3.2 (IIRC)

Sebastien.
