Different behaviour between gcd and dmd

test:

void main()
{
    import std.array;
    const lines = ["abc", "def"];
    auto res = std.array.join(lines, "\n");
}

DMD: compiles and work
GCD: compile error:

test.d:6: error: template std.array.join cannot deduce function from argument types !()(const(immutable(char)[][]), string), candidates are:
