Interesting, your example corresponds to my third case, the
linker error. I am on Window, building an x64 App, afaik in
that case the MS Visual Studio linker is used instead of
optilink. Will add your findings to the bug report.
Apparently Microsoft's C++ compiler doesn't mangle `float
arg[3]` parameters identically to `float* arg`:
void cppSArray(float color[3]) => ?cppSArray@@YAXQEAM@Z
void cppPtr(float* color) => ?cppPtr@@YAXPEAM@Z
The worst part about that is mangling aside, the two
declarations are identical to the compiler.

In this context, can anybody explain [1], in particular, in this
case, one should extern( C++ ) void cppSArray( ref float[3] color
);
instead of:
extern( C++ ) void cppSArray( float* color );
Others and me in this discussion seem to agree that parameter
(float color[3]) is equivalent to (float* color) in C++ world.
