--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
It seems as if for

  !$acc enter &
  !$acc   data
  !$omp flush &
  !$omp   RELEASE

a flag is wrong after parsing the second line; I think either the
'openacc_flag' needs to be (re)set to 0 or continue_flag needs to be set to 0.

(likewise for swapping omp and acc lines) 

Possibly be caused by the following commit as it works with GCC 11 but fails
with GCC 12:
  r12-1216-g4facf2bf5b7b32f444da864306b5c11e14c15bcf
