[4591] | 2879 | !-- The intention of the following loop was to let the compiler do the copying on return. |

| 2882 | !-- for INTENT(IN) variables (wrd_mpi_io_surface_2d). For INTENT(OUT) like in this case the code |
---|
| 2883 | !-- works on pgi compiler. But both, the Intel 16 and the Cray compiler show wrong answers using |
