Bug ID: 99477
Summary: CONTIGUOUS assumed-shape dummy not working with
associate construct
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: townsend at astro dot wisc.edu

Example program
I think I've stumbled on a bug with gfortran's handling of the CONTIGUOUS
attribute in assumed-shape dummy arguments, when the actual argument is an
array slice set up using an ASSOCIATE construct.
The example program demonstrates the issue. When compiled with gfortran 10.2.0,
I get the following output:
1 3 5 7 9
1 3 5 7 9
1 2 3 4 5
1 3 5 7 9
(note the third line, which has only stride 1). Whereas, I believe the output
should be
1 3 5 7 9
1 3 5 7 9
1 3 5 7 9
1 3 5 7 9
The issue goes away if I remove the CONTIGUOUS attribute from the function
argument.
cheers,
Rich
