--- Comment #2 from Paul Thomas <pault at gcc dot gnu.org> ---
Hi Andrew,

The testcase gives the same result if 'n' in the main program is a pointer.
However, if the dummy is given the allocatable/pointer attribute, as
appropriate, then the correct result is obtained.

Otherwise, using select type works correctly too.

Please use either of these as a temporary workaround.

I am hunting for where the dummy attribute has been missed in testing for the
need for pointer arithmetic in accessing the array elements.

Thanks for reporting this.

Paul
