Hi,

I have the following situation:

template<typename T, int i> class A
{
     A(){}
};

class B
{
public:
     B(A<double,3> arg=A<double,3>()){}
}

The above is pseudo-code and compiles on VS but not on gcc. Gcc
complains about the "3" in the default argument. But if I write

class B
{
public:
     typedef A<double,3> AD3;
     B(AD3 arg=AD3()){}

there is no problem. Obviously it has to do with the template
instantiation? But why is only the "3" that creates the problem?

Thanks a lot!
}
