Hi Harald,
I spend yesterday about two hours with this. Now I am still
tired but understand more. I think the confusion between the
two of us is due to wording and in which directions the
thoughts then go:
Talking about coindexed, all of a[i], b[i]%c and c%d[i] are
coindexed and there are many

Since the last libgfortran/Makefile.am commit,
https://gcc.gnu.org/g:13beaf9e8d2d8264c0ad8f6504793fdcf26f3f73
the ISO_Fortran_binding.h file is no longer copied to
$(build)/.../libgfortran/include/ – which breaks in-build-tree testing.
The Makefile does contain the rule:
ISO_Fortran_binding
Now I actually tested the patch – and fixed some issues.
OK? – It does add support for 'allocated(a[i])' by treating
it as 'allocated(a)', as 'a' must be collectively allocated
("established") on all images of the team.*
'a[i]' is (probably) an allocatable, following Malcolm in

Hi Tobias,
I think I can follow now what you are thinking, and I also had some
thoughts about what you be done in principle.
I was struggling the way I did because of:
(1) Intel rejects the code in the PR. For my previous patch,
% ifort coarray_allocated.f90 -coarray
coarray_allocated.f90(8):
When adding the initializer for an array, we need to make sure that
array bounds are properly simplified if that array is a PARAMETER.
Otherwise the generated initializer could be wrong and screw up
subsequent simplifications, see PR.
The minimal solution is to attempt simplification of array boun
