> I believe the program below is well-formed (according to 14.7.2, p9, an explicit instantiation does not constitute a use of a default argument). It fails to compile with XLC++ 8.0.
> $ cat t.cpp && xlC -qversion && xlC -c t.cpp
> template <class T> struct A { void foo (T = T::foobar ())
> { } };
> struct B { };
> template class A<B>;

> "t.cpp", line 1.45: 1540-0063 (S) The text "T::foobar" is unexpected.
> "t.cpp", line 3.16: 1540-0700 (I) The previous message was produced while processing "struct A<B>".
