I don’t know how to “read” the test, but it seems that this warning can be triggered if CS base/limit cause a #GP exception when EIP is loaded. I think it safe to remove this warning (which I introduced) as well as the redundant “return rc” that follows it. The code should handle the emulation correctly regardless of the warning.
