Bug ID: 89969
Summary: [OPENACC] private clause does not work with fortran
automatic array
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: abidh at codesourcery dot com
Target Milestone: ---
Please look at the test case below. It uses an automatic array in private
clause. With -fopenacc and ptx offloading, the resultant executable crashes at
run time with the following error:
libgomp: cuStreamSynchronize error: an illegal memory access was encountered
subroutine crash1(ngas)
implicit none
integer, intent(in ) :: ngas
integer, dimension(ngas) :: automatic_array
integer :: ilay
!$acc parallel loop private(automatic_array)
do ilay = 1 , ngas
automatic_array(ilay) = ilay
end do
end subroutine crash1
program main
implicit none
integer :: ngas = 10
call crash1(ngas)
end program main
