I didn't notice it.  Yet I still crashed on the Release version.  CGAL 
seems to be very very slow in Debug mode (I use MSVC 2008 x64 on Windows 
7 x64).  Do you know of any way to speed up debugging?  I don't want to 
report a bug unless I can tell my surfaces are good.  I keep getting 
crashes with certain surfaces even though I've removed disconnected 
components and degenerate faces, and CGAL tells me the polyhedron is 
valid.  The surfaces are heavily sampled, so the code takes a while...
Any pointers are appreciated!
Thanks,
JB
