[Bug c++/38265] New: STL treats explicit constructors as converting constructors

["konto dot dydaktyczne at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

When some STL containers are created, explicit constructors for contained
objects are treated as converting constructors. The keyword "explicit" is
ignored, and no error message is issued; see the code.

#include <vector>
#include <deque>

class X {
        public:
                explicit X(int) {}
};

int main() {
        int a[1] = {};
        std::vector<X> v(a, a + 1);
        std::deque<X> d(a, a + 1);
}
