Huh, that's weird. Did you actually encounter this happening, or is this
some sort of patch based on the output from a tool?
I ask because I don't see how this could ever actually report a
constant, when the array it loops over only has a single element.
Feels like we should just do something like the following (if we do
anything at all)

Cheers,
