<pre>Hello!
Following code compiles successfully with clang (because it does not invoke 2nd
constructor), while gcc fails (on static_assert, trying to actually call 2nd
constructor).
#include <initializer_list>
#include <cstdio>
template<typename T>
class II
{
public:
II(std::initializer_list<int> l1)
{
printf("one list\n");
}
II(std::initializer_list<int> l1, std::initializer_list<int> l2)
{
static_assert(sizeof(T) == 0, "");
printf("two lists\n");
}
};
int main()
{
II<int> i1{ { 1 }, { 2 } };
II<int> i2{ { { 1 } }, { { 2 } } };
return 0;
}
If clang's behaviour is correct, how do I call 2nd constructor (assuming that I
need to call it with single-element list)?</pre>
