[Bug fortran/40551] Wrong code due to missing copy-in/copy-out stried array to assumed-size dummy

[burnus at gcc dot gnu dot org]

I think I would go for option (b) of creating a new array descriptor, which is
then used for copy out. The place where currently the creation of a temporary
is prevented is:
  gfc_trans_arrayfunc_assign

If the return symbol is assumed shape, deferred shape (pointer, allocatable) or
the actual is known to be contiguous (whole array, which is not an
assumed-shape/deferred-shape dummy) one can continue as is, otherwise one needs
to pack the arrays. (Todo: Check that no copy in happens.)

At some point, we need a contiguous check - also for F2008's CONTIGUOUS
attribute.
