ucobound(A, dim=1) == 6 ? Otherwise I'm even more confused.
Sorry

Well, the current implementation supports effectively only a single
image - for -fcoarray=single on purpose and for -fcoarray=lib because it
has not yet been implemented.
Later, one has to add some function call for "scalar[]"
while "scalar" itself is

Yes and no. In terms of the language, they are scalars - but they have a
codimension, e.g.
integer, save :: A[4:6, 7:*]
is a scalar variable on each image, but it has a coara

Sorry for pinging again, but the patch is large enough to block a bit my

I found a test case (part of Reinhold Bader's fortran_tests), which gave
