           Summary: GCC adds an address-of somewhere!
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: d...@boost-consulting.com


Compile the following:

template <class X, X g>
struct A 
{
        A() { float r = g(0); }
};

struct f_t
{
    float operator() (float x) const { return 1; }
};

f_t f;

A<f_t&, f> x;

Now replace "g(0)" with "(*g)(0)".  It compiles!

It's almost as though I had written

A<f_t*, &f> x;
