           Summary: Findloc does not find the result of a function with a
                    deferred-length character return value
           Product: gcc
           Version: 13.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

Created attachment 58705
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58705&action=edit
testcase

Invoking findloc with an array of character values and a search value obtained
by a function call (which returns a deferred-length character value) always
yields 0, even if the value is present in the array.

Thanks for checking and looking up. I have not been able to use gfortran-14 due
to bug 114874 (a regression which has been resolved after release). Strangely,
the search box of bugzilla does not show relevant findloc issues, so I missed
bug 110288.

The original issue was reported for findloc, but did occur with several other
intrinsics accepting deferred-length character.  If you edit the bugzilla
search to include resolved issues, you will also see the mentioned one.

You have several options to go beyond 13.1:
- try upgrading to 13.3
- wait for the upcoming 14.2 release (expected soon)
