--- Comment #2 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Reproduced, thanks for the report.


The problem disappears when adding '-fno-ipa-pta' to '-O1 -fopenacc
-fstack-arrays'.  Not yet analyzed the differences.


The problem does not reproduce with '-O1 -fopenmp -fipa-pta -fstack-arrays'=
 and
code changes as per:

    -    !$acc parallel copyout(array)
    +    !$omp target map(from:array)
         array =3D [(-i, i =3D 1, nn)]
    -    !$acc end parallel
    +    !$omp end target

..., so really points to something specific to OpenACC handling.=
