        * dependency.c (gfc_dep_resolver): Coarray indexes are to be ignored
        during dependency computation.  They define no data dependency.
        * trans-array.c (conv_array_index_offset): The stride can not be set
        here, prevent fail.
        * trans-intrinsic.c (conv_caf_send): Add creation of temporary array
        for caf_get's result and copying to the array with vectorial
        indexing.
