BTW, pgf90 DOES NOT generate an error on plain subroutine (x) real(DP), allocatable, dimension(:) :: x for me, hust when allocatbale was mixed with optional or intent attribute. How to prevent Beamer from repeatedly expanding macros in \frametitle when frame-breaking Why can't I do ls -a 1>&-? As an alternative, use intent(inout). Intel compiler is very good in implementing all the extensions described in this chapter.

A second variable is introduced to nullify the pointer on first entry so that its status can be safely tested. It's not really a bug, because the program is not standard conforming, but why does it still work? These are incompatible as the first implies a dummy argument and the other specifies a named constant.

Posted: Wed Sep 01, 2004 2:51 pm Post subject: Problem with program using language extensions I guess that's one problem with programing using non-stanard language extensions, portability can prove difficult. Again the intention is that this promise will encourage vendors to implement the feature in their compilers, confident that their efforts will have a secure future. We welcome your contributions and experiences so that we can share your pain. The Standard says (12.4.1.2, Actual arguments associated with dummy data objects): "If a dummy argument is allocatable or a pointer, the associated actual argument shall be polymorphic [etc etc]".
