Public bug reported:
Struct A declares a function 'f' with a parameter of type typename
std::integral_constant<size_t,0>::type.
Struct B inherits class A and declares a function with a parameter of type
typename std::integral_constant<size_t,1>::type and the same name 'f'.
A::f is not accessible.
struct A
{
static void f(typename std::integral_constant<size_t,0>::type){}
};
struct B: public A
{
static void f(typename std::integral_constant<size_t,1>::type){}
};
void tst()
{
B::f(std::integral_constant<size_t,0>::type());
}
error: no matching function for call to ‘B::f(std::integral_constant<long
unsigned int, 0>::type)’
no known conversion for argument 1 from ‘std::integral_constant<long unsigned
int, 0>::type {aka std::integral_constant<long unsigned int, 0>}’ to
‘std::integral_constant<long unsigned int, 1>::type {aka
std::integral_constant<long unsigned int, 1>}’
