The listing in the WP34s library is from 8.4.2012, wheras the program in the HP-forum article has been updated on 30.8.2013.

The date does not tell the whole story. ;-)

Take a look at the code. The one in the articles forum does not include several obvious improvements, e.g. using RCL arithmetics, replacing EEX CHS 3 ENTER 2 x with a simple 2 SDR 003 and several other changes that have been discussed back then. Maybe the only update was a slight edit to make it run with v3.2 ?

BTW the polyroot.wp34s version I got is dated 12.12.2012, i.e. eight months later than yours.
However, both versions should return correct results, at least for such a simple case. I still assume something has been entered incorrectly.
