The following reduced testcase from libgomp.fortran/non-rectangular-loop-1.f90
fails execution:
program main
integer :: n,m,p, i,j,k,ll
n = 11
m = 23
p = 27
!$omp simd collapse(3) lastprivate(k)
do i = 1, n,2
do j = 1, m
do k = 1, i + 41
if (k > 11 + 41 .or. k < 1) error stop
end do
end do
end do
if (k /= 53) then
print *, k, 53
error stop
endif
end
