Hi,
the following code fails to compile with gcc-4.3-20080215
template <class T=int, class... ARGS>
struct test {};
int main()
{
test<> a;
return 0;
}
According to N2242 section 3.6, page 7:
If a template-parameter of a class template has a default template-argument,
each subsequent template-parameter shall either have a default
template-argument supplied or be a template parameter pack. If a
template-parameter of a class template is a template parameter pack, it must be
the last template-parameter.
The compiler issues the following error: no default argument for ARGS at
line 1 above.

parameter with default type.
