------- Comment #5 from rguenth at gcc dot gnu dot org 2008-01-24 15:52 -------
Reduced (invalid?) testcase:
template <class Real, class Policy> struct precision {
typedef typename Policy::precision_type precision_type;
};
template <class T1, class T2, class Policy>
struct bessel_traits {
typedef T1 result_type;
typedef typename precision<result_type, Policy>::type precision_type;
};
template <class Fn>
void
def(char const* name, Fn fn);
template <class T1, class T2, class Policy>
typename bessel_traits<T1, T2, Policy>::result_type
cyl_bessel_j(T1 v, T2 x, const Policy& pol);
void hedge_expose_polynomial()
{
def("cyl_bessel_j", cyl_bessel_j<int, double>);
}
EDG says
ice.1.min.cpp(20): error: no instance of function template "def" matches the
argument list
argument types are: (const char [13], <unknown-type>)
def("cyl_bessel_j", cyl_bessel_j<int, double>);
