Compiler ICE's when calling a template function belonging to a template base
class using an explicit parameter list. That was a bit obtuse...an example will
help:
class E inherits from class A<E> and class B<E>. ICE occurs when class B<E>
downcasts itself to E:
Derived * e = static_cast<Derived *>(this);
and tries to call a function in A<E> using the syntax:
e->A<Derived>::template f<int>();
It compiles fine when the A<Derived>:: scope is not used, and when e is first
cast to (A<Derived> *).
e->template f<int>();
static_cast<A<Derived>*>(e)->template f<int>();
On a related note, neither of these work at all without the "template" keyword,
but I'm not sure whether that is a bug, or just my ignorance of the standard.
Contact me if you want me to file a bug on that.
