            Bug ID: 101310
           Summary: Bind(C): CFI_section seems confused by pointer arrays
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libfortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sandra at gcc dot gnu.org
  Target Milestone: ---

Many of the unit tests for CFI_section included in the WIP TS 29113 testsui=
te
are failing.

https://gcc.gnu.org/pipermail/gcc-patches/2021-July/574115.html

At least some of the problems seem to be related to handling pointer arrays
where the lower bound may be nonzero; e.g. section-1p and section-2p fail, =
but
the corresponding non-pointer cases sharing the same C code pass.

The set of tests that seem affected by this bug are:

library/section-1p.f90
library/section-2p.f90
library/section-3.f90
library/section-3p.f90

and also

interoperability/fc-out-descriptor-7.f90

which tries to pass the result of CFI_section back to Fortran via an
intent(out) argument (the unit tests only manipulate it in C code).=
