Bug ID: 78815
Summary: ICE: segfault with -fopenmp -fsanitize=address
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gerhard.steinmetz.fort...@t-online.de
Target Milestone: ---
Follow-up of pr77973, since about 20161113.
An example with an automatic explicit-shape array :
$ cat z1.f90
subroutine s(n)
integer :: i, n, z(n)
!$omp target
!$omp parallel do
do i = 1, n
z(i) = 1
end do
!$omp end target
end
$ gfortran-7-20161211 -fsanitize=address -fopenmp -c z1.f90
