Hello,

I used DJGPP and CYGWIN to compile the following code. DJGPP runs as
expected while CYGWIN reports

Program received signal SIGSEGV, Segmentation fault.
0x6105b0f3 in _size_of_stack_reserve__ ()

Please help solve the problem. It seems the Segmentation fault happens
after the cout << line. However, there is something wrong before the
cout << line because the output data are corrupted.

// code follows, I've removed some lines that I think is irrelevant.
#include <iostream.h>

template < class T >
class a
{
	private:
	public:
		T* t;
		a(void) {t=new T[256];};
		~a(void) {delete[] t;};
		template < class U > a<T> & operator = (const a<U> &v) 
		{
			int i;
			for(i=0;i<256;i++)
			{
				t[i]=T(v.t[i]);
			}
			return *this;
		};
		void fill ( const T & h) { ... };
		a<T> duplicate(void)
		{
			a<T> temp;
			temp=*this;
			return temp;
		};
		friend ostream & operator << <T> (ostream& out, const a<T>& t);
};

int main(void)
{
	a<int> b;
	a<float> c;
	a<float> d;
	b.fill (99);
	c.fill (88.888);
	d=b;
	b=c;
	c.duplicate();
	cout << b << c << d;
	return 0;
}
