--- Comment #5 from janus at gcc dot gnu.org 2011-08-14 12:07:55 UTC --- (In reply to comment #2) > ifort rejects the original test case with: > > error #6756: A COMMON block data object must not be an automatic object. [Z] > common n,z > -----------^ ifort's error message is apparently based on this restriction in the F08 standard: "C5100 (R569) A common-block-object shall not be a dummy argument, a result variable, an allocatable variable, a derived-type object with an ultimate component that is allocatable, a procedure pointer, an automatic object, a variable with the BIND attribute, an unlimited polymorphic pointer, or a coarray." This is what really makes the original test case invalid.
