------- Additional Comments From bangerth at dealii dot org  2003-11-06 22:56 -------
Confirmed. Here's something smaller:
---------------------
struct Test {
    static void fun();
};

template <void (*fun)()>
void foo () { (*fun)(); }


template
void foo<Test::fun> ();
-------------------------------

This is a regression on mainline w.r.t. all previous versions.

Looks like when the new parser went in. :(
