garbett@utknp3.phys.utk.edu (Garbett) wants to know why he
is getting segmentation fault in the following code:

:#include <iostream.h>
:
:class list
:{
:	private:
:		int	num;
:		list	*next;
:	public:
:		// Constructors
:		inline list() { next = NULL; num = 0; }
:		inline list(int the_num) { next = NULL; num = the_num; }
:		inline list(list *next_node) { next = next_node; num = 0; }
:		list(int the_num, list *next_node)
:			{ next = next_node, num = the_num; }
:
:		// Normal Usage
:		inline void	display_value() { cout << num; }
:		inline list *get_next()		 { return next; }
:
:		// Recursive function and culprit of core dump
:		void print_all() ;
:};
:
:void list::print_all()
:{
:	cout << num << "\n";
:
:	if( next != NULL)
:		next->print_all();
:}
:
:int main()
:{
:	int	i;
:	list	*top, *curr;
:
:	for(i=0, top = NULL; i<10; i++)
:		top = new list(i, top); 
:
:	curr = top;
:
:	/* This works */
:	do
:	{
:		curr->display_value();
:		cout << "\n";
:		curr = curr->get_next();
:	} while (curr != NULL);
:
:	cout << "\n" << "Testing Recursive Function\n";
:
:	/* Get ready for a segmenatation fault */
:	curr->print_all();

curr is 0 when you are  call print_all(). Hence, you are getting
the segmentation fault.
