The below example gives a 'Program c++ got fatal signal 6.' under
g++ version 1.34.2.
---------
#include <String.h>

	String blurb("bleah");

class Foo
{	String a;
public:
	Foo()	{}
	virtual void scooby(String s=blurb)			{a=s;}
	virtual void doobie(String s=String("bleaurgh"))	{a=s;}
};

class Bar : public Foo
{	String b;
public:
	Bar()	{}
	virtual void scooby(String s=blurb)			{b=s;}
	virtual void doobie(String s=String("bleaurgh"))	{b=s;}
		// Above line causes problem
};	

main()
{	Foo x;
	Bar y;

	exit(0);
}
----------
Commenting out the 'doobie' member function of 'Bar' eliminates this.
I'm not sure if this sort of default arg. should be allowed anyway since
the two 'String("bleaurgh")'s are effectively different things, but obviously
an error message of some sort is preferable
