Sorry, can't help you on this one.  The -frepo doesn't help here, either.

Well, maybe if you could let us look at the actual code where you have
trouble, we can help you better?

But sir, why make 'ptr' a (void *)?  Why not a (T *)?  I.e.

template<class T>
class test
	{
	T *ptr;
public:
	int setptr(int size)
		{ ptr = new T[size]; }
	};

int
main()
	{
	test<int> object;
	object.setptr(10);
	return 0;// memory leak!!!
	}

This is an obvious solution.  Since you didn't use it, there must be
some reason in your original code which prevented you from using this
class definition.  Maybe if you described your problem, you might get
better results.  Good luck!
