Summary NeverDestroyed<> constructor does not pass std::initializer_list correctly

Created attachment 278325 [details] TestCase.cpp The following code fails to compile: #include <wtf/NeverDestroyed.h> #include <wtf/Vector.h> int main() { Vector<int> v1 = {1, 2, 3}; // OK NeverDestroyed<Vector<int>> v2 = {1, 2, 3}; // "error: no matching constructor for initialization of 'WTF::Vector<int, 0, WTF::CrashOnOverflow, 16>" return 0; } This is likely because the "std::forward<Args>(args)..." in the NeverDestroyed constructor unrolls the initializer_list into a sequence of parameters, rather than passing it unadulterated.
