Below is a short program that exploits what I think is a bug in the G++
compiler.  I am using g++ 1.36.1 on SunOS 3.5.  The bug calls a method that
requires an (alpha*) when a (void*) is passed to it.  I would have thought
that the compiler should flag this as a function call for which an invalid
argument type was passed.  Am I wrong?

--------Code begins--------
#include <stream.h>

class alpha {
	static int	x = 0;

public:
	alpha() { x = x + 1; }
	~alpha() {}

	void print(alpha*);
};

void alpha::print(alpha* n) {
	cout << "X = " << x << " ";
	if (n != 0)
		n->print((void*) 0);
	cout << ";";
}

int main(int argc, char *argv[])
{
	alpha	test1;

	test1.print((void*) 0);

	alpha	*test2 = new alpha;

	test1.print(test2);
	cout << "\n";
}
