            Bug ID: 103154
           Summary: Crashing gfortran due to bad type parameter
                    specification
           Product: gcc
           Version: 10.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: b.j.braams at cwi dot nl
  Target Milestone: ---

The following code is bad, it uses the undeclared variable k. This causes
gfortran to crash with an error message requesting the issue to be reported. I
obey.

Yes (anlauf), this looks like the same error as was reported by Berke Durak on
2018-01-10, Bug 83762 - ICE on variable declaration with undefined PDT
parameter.
