            Bug ID: 100602
           Summary: Erroneous "pointer argument is not associated" runtime
                    error.
           Product: gcc
           Version: 11.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: here.is.a.gcc.bug at gmail dot com
  Target Milestone: ---

Created attachment 50813
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50813&action=edit
A minimal broken example. (14 lines)

Compiling with -check=all gives a runtime error "Pointer argument `this` is not
associated"

This only happens using gfortran-11.1.

I'm unsure if this is this bug [1]

Confirmed.  The error message is bogus.

This looks like a regression.

    Fortran: Fix erroneous "pointer argument is not associated" runtime error

    which runtime check to generate.

Fixed on mainline for gcc-12 and on 11-branch.  Closing.

Thanks for the report!
