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 testsuite
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).
