[Bug fortran/33745] New: -fbounds-check: Bogus out-of-bounds run-time error for assumed-size array

[burnus at gcc dot gnu dot org]

In the following subroutine "findphase", the upper bound of the second
dimension of "jp" is not known. Using -fbounds-check:

Fortran runtime error: Array reference out of bounds, upper bound of dimension
2 of array 'jp' exceeded, 2 is greater than 0


 implicit none
 integer, parameter :: maxss=7,maxc=8
 integer :: jp(2,maxc)
 call findphase(jp)
contains
  subroutine findphase(jp)
    integer, intent(out) :: jp(2,*)
    jp(2,2:4)=0
  end subroutine
end

>From the dump, one sees that the error is printed unconditionally and twice.

findphase (jp)
