<pre>Testcase is this (also found at <a href="https://godbolt.org/z/iO4IL7">https://godbolt.org/z/iO4IL7</a> )
#include <initializer_list>
class T {
public:
int c;
T(int c) : c(c) {}
};
extern void f(std::initializer_list<T>&);
void test() {
T t(666);
std::initializer_list<T> a({t});
//std::initializer_list<T> a{{t}};
f(a);
}
Something to note is that using the commented out version will work fine.
I think both versions should be OK as "t" will still be live until the end of
the scope.</pre>
