Most of the drivers don't set up the maximum value in the query info. So
when later hud_pane_set_max_value() is invoked, we are using a rather
"random" number.
Turns out that in some 32bit cases, this random number is big enough
that `leftmost_digit` is 0 because DIV_ROUND_UP() overflows, aborting
with an assertion.
