Not totally unexpected.

Actually more worrying than the fact that it gives an error in
dviluatex is that it does
the wrong thing without error in luatex it's comparing the number to
140 but luatex
sets this (somewhat arbitrarily) to 40 so even when it is set in pdf
mode the numeric
test is meaningless.

the "40" might be an issue for luatex but anyway the main issue is
that hyperref shouldn't
be testing this at all in luatex now. I'll see what I can do.

better than this list for hyperref specific issues.
