           Summary: arith.c:2009: bad statement order ?
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

trunk/gcc/fortran/arith.c:2009]: (style) Statements following return, break,
continue, goto or throw will never be executed.

Source code is

static bool
wprecision_int_real (mpz_t n, mpfr_t r)
{
  mpz_t i;
  mpz_init (i);
  mpfr_get_z (i, r, GFC_RND_MODE);
  mpz_sub (i, i, n);
  return mpz_cmp_si (i, 0) != 0;
  mpz_clear (i);

}

Suggest either delete the mpz_clear or use it.
