This seems very odd to me as well. Both i and num_subrects are guint8s, so any
value num_subrects could possible take will also be reached by i, ending the
loop (since the conditional is < not <=).

Potentially a compiler bug that is promoting num_subrects for optimization
without checking properly? Even so, it's assigned the result of
tvb_get_guint8() which can't return more than 255 anyways.
