--- Comment #3 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
A simplified version down the way from another source
with an allocatable variable appearing in a private clause :


$ cat z1.f90
program p
   integer, allocatable :: z
   integer :: i
   !$omp do private(z)
   do i = 1, 2
      z = i
   end do
end


$ gfortran-7-20161113 -fopenmp z1.f90
z1.f90:4:0:

    !$omp do private(z)
