Bug ID: 100965
Summary: [OpenMP] ICE: Error: incorrect sharing of tree nodes
Product: gcc
Version: 12.0
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: ---
Found when working on 'defaultmap' (related: PR90742, PR92568).
The following gives an ICE:
SAVE_EXPR <.strxa.6>
#pragma omp target num_teams(1) thread_limit(0) map(tofrom:*strxa [len:
SAVE_EXPR <.strxa.6>]) map(alloc:strxa [pointer assign, bias: 0]) map(to:.strxa
[len: 8]) [child fn: MAIN__._omp_fn.1 (.omp_data_arr.7, .omp_data_sizes.8,
.omp_data_kinds.9)]
during GIMPLE pass: cfg
foo.f90:8:14: internal compiler error: verify_gimple failed
0xf8b4e1 verify_gimple_in_cfg(function*, bool)
../../repos/gcc/gcc/tree-cfg.c:5509
but only when used in two separate target regions:
implicit none
character(len=:), allocatable :: strXa
!$omp target
strXa = ""
!$omp end target
!$omp target
strXa = ""
!$omp end target
end
