Bug ID: 106730
Summary: [OpenMP] ICE in install_var_field, at omp-low.cc:797
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, openmp
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
Created attachment 53499
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53499&action=edit
Slightly modified and de-module-used testcase; run as 'gfortran -fopenmp
test.f90'
Found via
https://github.com/SOLLVE/sollve_vv/blob/master/tests/5.0/target/test_target_mapping_before_alloc.F90
Testcase fails since at least GCC 9.
$ gfortran -fopenmp test.f90

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Okay – that's the
‘member’ appears more than once in map clauses
issue
For C/C++, there is this error – for Fortran not:
error: ‘member’ appears more than once in map clauses
(same for 'a' and 'scalar') using the C testcase at
https://github.com/SOLLVE/sollve_vv/blob/master/tests/5.0/target/test_target_mapping_before_alloc.c
for the C/C++ testcase.
I think one pending patch was addressing on this.
Indeed, using devel/omp/gcc-12 (OG12), it compiles + runs for Fortran -
but still fails for C/C++ with the "more than once" error.
I think it is part of the following patch set:
* [PATCH 00/16] OpenMP: lvalues in "map" clauses and struct handling rework
https://gcc.gnu.org/pipermail/gcc-patches/2021-December/586600.html
and January + February updates (search for metadirective)
+ patch review end of May, e.g.
https://gcc.gnu.org/pipermail/gcc-patches/2022-May/595762.html (+ 4 more
emails)
