As a work around, we can use Ali's variant and pragma(mangle, "mangle_string"). I found my "mangle_string" with dependency walker.

I think this is no DMD bug. The problem is that Microsoft unlike gcc mangles the `float color[3]` variant as `float * const color`, which can't be represented in D directly (const pointer to mutable data).

So the proper workaround for MSVC targets would be:

C++:

bool cppFunc(float color[3])
{
    for (int i = 0; i < 3; ++i) color[i] *= 2;
    return true;
}

D:

pragma(mangle, "?cppFunc@@YA_NQEAM@Z")
extern(C++) bool cppFunc(ref float[3] color);

void main()
{
    float[3] my_color = [ 1, 2, 3 ];
    cppFunc(my_color);
    assert(my_color == [ 2, 4, 6 ]);
}

To get the same results in C++ and D:

C++:
  void cppFunc(float (&color)[3]) { }

D:
  extern(C++) void cppFunc(ref float[3] color) { }

Both mangle to:
  ?cppFunc@@YAXAAY02M@Z
