BTW I intended to show it for arrays with undefined length such as:

        dimension a(10)
        call sub(a,10)
        end
        subroutine sub(a)
        dimension a(*)
        a(5) = 5
        end

FSF GDB recognizes the dynamic length (former example) as undefined length
	type = real(kind=4) (*)
while FSF GDB recognizes the undefined length (latter example) as -1
	type = real(kind=4) (-1)
which does not work in any case.

For VLA GDB the former example gets the correct length
	type = real(kind=4) (10)
while VLA GDB recognizes the undefined length correctly:
	type = real(kind=4) (*)

So that your patch could be compatible with both.


Thanks,
