Oops?

Compiler is g++ (GCC) 4.2.4 (Ubuntu 4.2.4-1ubuntu4)
(from Ubuntu 8.04 LTS)

Boost libraries (1.40) and CGAL (3.7 final) are self-compiled.

I'm compiling the demo with the command

    g++ -frounding-math -O3 distance_browsing.cpp -lCGAL

Optimization level seems not to be the issue, -O0 triggers the assertion
too.  I added -frounding-math since CGAL notified me to do so.  Any
other flags one should use?

Related stuff:
