[Bug c++/35497] New: Compiling error with template part. spec. involving function call and >>

[rodolfo at rodsoft dot org]

The following code gives a compiling error with gcc-4.3.0 with -std=c++0x:

template <class T> class A {};
template <class T> class B {};
template <class R, class X1> class A<B<R(X1)>> {};

main.cpp:3: error: a function call cannot appear in a constant-expression

While if we use > > (instead of >>) in the class specialization, it compiles
fine, as in:

template <class T> class A {};
template <class T> class B {};
template <class R, class X1> class A<B<R(X1)> > {};
