Hi,

I'd like to run a CGAL'ed program in Valgrind. As I know already from
the past, this does not work very well. Are any compiler-switches or
Valgrind-options known to overcome the problems? I use gcc (4.4.3) and
CGAL3.6.0 on 64bit Linux:

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: /opt/CGAL360/include/CGAL/Interval_nt.h
Line: 158
Explanation: Wrong rounding: did you forget the -frounding-math option 
if you use GCC?

...where -frounding-math is used, and the program works flawlessly
outside Valgrind.

Best
Bernhard
