Given:

struct A {
    void mf() {}
};

int main()
{
    void (A::*pmf)() = &A::mf;
    A a;
    a.*pmf();   // should be (a.*pmf)();
}

mainline GCC says to use .* or ->* to use the PMF,

pfm_diag.cc: In function 'int main()':
pfm_diag.cc:9: error: must use '.*' or '->*' to call pointer-to-member function
in 'pmf (...)'

This is unhelpful if you don't know the right syntax, because the correct
operator _is_ present, but the compiler is complaining about the expression to
the right of the operator.  Maybe it would be better if the error message had a
complete example after it:

pfm_diag.cc: In function 'int main()':
pfm_diag.cc:9: error: must use '.*' or '->*' to call pointer-to-member function
in 'pmf (...)', e.g. '(a.*f) (...)'
