--- Comment #1 from Philip Hazel <ph10@???> ---
The bug was in computing the minimum length of a group when one of its branches
exceeded 65535, which is the maximum minimum length that is recorded. Here is a
simple patch that fixes this, but inelegantly. I have committed a somewhat more
elegant patch to the development source. Thank you for the report.
