Function x(b() As Double) As Integer
	'' The captured bounds are compared before the function calculates a length.
	'' FB-LINTER: DISABLE-NEXT-LINE FBL-ARR-004

	Dim As Integer upper_bound = UBound(b)

	If upper_bound < lower_bound Then Return 0

	Return upper_bound - lower_bound + 1
End Function

Dim a(1 To 10) As Double
Print x(a())
Dim c(10 To 20) As Double
Print x(c())
