Broken exceptions in Lion/XCode?

Question

Having upgraded to Lion and noticed that gcc had been removed,
I downloaded the free verson of XCode from the App store.
gcc was restored ... but the exceptions are behaving funny.
Basically, if I throw any exception (with any message) I get
the following text in the terminal:
terminate called throwing an exceptionAbort trap: 6
(with a noticable pause before displaying "Abort trap: 6"
Anybody else hit this (and found a way around it, even better)?
Thanks in advance.

Here was my minimal code:
#include <stdexcept>
int main()
          throw std::runtime_error( "Doesn't display this message" );
          return 0;
For all it's worth, I've found a way around it, essentially just to
catch all exceptions before exiting, something like:
#include <stdexcept>
int main()
     try
          // Call main program here which may throw exceptions
          throw std::runtime_error( "Doesn't display this message" );
     catch( exception &e )
          std::cerr << "Error: " << e.what() << std::endl;
          return 0;
Whatever's changed in the latest XCode and/or Lion doesn't seem to like
uncaught exceptions.
I've never used CGAL, but I'm guessing a similar work-around will
work there as well.
