Could it be that you are using an older version of CGAL with a recent 
XCode (one where g++ uses llvm as a backend)? llvm can't handle rounding 
properly. We introduced a workaround for it, which should be in the latest 
version, but I can't remember what version it first appeared in.

Uncaught exceptions should print more than that, probably another 
llvm-related limitation.
