There are other cases where this is the case (e.g. ∑+ and ∑-) and this behaviour makes sense.
Since it's documented it's definitely not a bug.
Compare this with the CHS and Stack Lift bug:

Quote:However, I have discovered that CHS only seems to enable stack lift on the 11C and 34C when the operand in the X register is not zero.

Quote:My first time beaten by this type of "feature" is with RCL (Yes, it is also documented)
Say, 5 is stored in memory 0, with a clear stack:

5 * 5: RCL 0 Enter x => 25 -- so far so good
5 * 4: RCL 0 Enter 1 - x => 100 -- ???

This has nothing to do with RCL 0. You get the same result if you just enter 5 instead. This is exactly the difference between ENTER on an HP-42S and an HP-48G for instance. We are familiar with these differences.

On the HP-42S you could use:

5 ENTER ×
5 ENTER ENTER 1 - ×

On the HP-48G you could use:

5 DUP ×
5 DUP 1 - ×

or then:

5 ENTER ENTER ×
5 ENTER ENTER 1 - ×
