Hi David:

The Last Change info is either bogus or it's referring to the last change of
SAS-mode before we integrated it into ESS; not very helpful at this point.
The fix for this bug is in 5.2.12 which should be out RSN.  In the 
meantime, if you
replace those 3 lines above with the following, recompile ESS if necessary,
and restart emacs then it should work:
    (comment-start                . "** ")
    (comment-start-skip           . "[*][*] ")
    (comment-end                  . " **;")
    (comment-end-skip             . " [*][*];")
