A modified and valid case which doesn't cause ICE:
template <typename LHS, typename RHS>bool operator<( LHS lhs, RHS rhs );
struct ComputedAttribute {
int descriptor();
};
class AttributeDescriptor {};
template <typename T, typename R>
struct less_member_2_m
{
typedef R (T::* T_mem_ptr) ();
T_mem_ptr mem_ptr;
template <typename R_alt>
bool operator()(R_alt & rhs )
{
T a;
return ( a.*mem_ptr )() < rhs ;
}
};
void computedAttribute( AttributeDescriptor & desc )
{
less_member_2_m<ComputedAttribute, int> m;
m.mem_ptr = &ComputedAttribute::descriptor;
m(desc);
}
Change the operator() to:
template <typename R_alt>
bool operator()(R_alt & rhs )
{
T a;
return ( a.*mem_ptr ) < rhs ;
}
causes the ICE.
