problem with g++-4.2 and g++-4.1

[Alpha]

Hi,

Can anyone tell the reason why the following code can be compiled
using g++-4.1 while g++-4.2 throws a compilation error?

template<class A, class B = int>
class foo{
public:
A i;
B j;
};

template<class A = int, template<class>class B = foo>
class bar : public B<A>{
public:
A k;
};

int main(){
bar<test;

test.k = test.j = test.i = 0;

return 0;
}

template <class A=int, template <class, class=int>class B = foo>

Thats the right way.

class bar : public B<A>{
public:
A k;

};

int main(){
bar<test;

test.k = test.j = test.i = 0;

return 0;

}
