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
an IC
This patch implemented the trans*.c part of allocatable scalar coarrays;
contrary to noncoarray allocatable scalars, they have cobounds and thus
use an array descriptor.
While there are still some bugs and minor omissions, gfortran slowly
gets feature compile with regards to single-image coarr
