That part is a bug at least in the compiler message. Is it
really an internal ctompiler error? Doesn't look like it: the
compiler is talking to us happily. :)
My simple test works for me:
// deneme.cpp
float cppFunc(float color[3]) {
return color[0] + color[1] + color[2];
}
$ g++ -c deneme.cpp -o deneme_cpp.o
// deneme.d
extern(C++) float cppFunc(float * color);
void main() {
float[3] my_color = [ 1.5, 2.5, 3.5 ] ;
assert(cppFunc(my_color.ptr) == 7.5);
}
$ dmd deneme_cpp.o deneme.d -of=deneme
Builds and runs fine... on Linux... I don't know whether that's
significant.

Btw, according to [1] your example should not work either, I
doubt that there is a difference between C and C++ interfacing,
it should be:
extern(C++) float cppFunc( ref float[3] color );
In my case its a linker error as well.
