Hi all,

here is a small patch to fix a problem with class-array-valued
functions, where the rank was not determined properly. Regtestes on
x86_64-unknown-linux-gnu. Ok for trunk?

[Note: This patch only fixes the rejects-valid problem of comment 0/1,
but not the ICE of comment 2/3, which is a completely separate issue.]

Cheers,
Janus
