[Bug fortran/45595] New: segfault on omp collapse

[jv244 at cam dot ac dot uk]

this test case (with an invalid collapse):

  SUBROUTINE init_input_type()
  INTEGER :: k,l(3),u(3)
!$omp parallel do shared(l,u) collapse(3)
    DO k = l(3),u(3)
    ENDDO
  END SUBROUTINE

leads to an ice with current trunk as:
