Inheriting an explicit constuctor

[Eugene_S_1]

Intel C++ compiler (Version 16.0.3.207 Build 20160415) seems to drop the explicit specifier when the constructor of the base class is inherited with using.

struct B
{
    explicit B(int) { }
};

struct D : B
{
    using B::B;
};

B b = 1; // Not OK, fine
D d = 1; // Not OK with Microsoft C++ and GCC, but OK with Intel C++
