Manipulating array descriptors from C?

Does it mean that, in contrast to a bind(C) user defined type, the C array descriptor is NOT identical to the internal array descriptor of gfortran? And that it is created and filled upon call?

Short answer is YES and YES.

OK, it explains everything, then… And it also explains why adding target doesn’t help, as the compiler has no way to avoid the pseudo copy-in/copy-out.
