Such a worthwhile feature that in IDL 5.6 a COMPILE_OPT keyword was
introduced to disable it!

STRICTARRSUBS - When IDL subscripts one array using another array as
the source of array indices, the default behavior is to clip any
out-of-range indices into range and then quietly use the resulting
data without error. This behavior is described in Array
Subscripting. Specifying STRICTARRSUBS will instead cause IDL to
treat such out-of-range array subscripts within the body of the
routine containing the COMPILE_OPT statement as an error. The
position of the STRICTARRSUBS option within the module is not
important: All subscripting operations within the entire body of the
specified routine will be treated this way.
