The case in which we throw, but have no handlers.  The overhead
ought to be zero, but it isn't.  Consider:

	extern double f(double a); 
	extern double e, value;
	void a()
	{
		if (e == 0)
		    throw 1;
		value = f(e);
	}

We get

   text    data     bss     dec
    261       0       0     261		-fsjlj-exceptions
    116      64       0     180		dwarf2 eh

One might simply consider this to be a bug in the implementation...
