the lattice computation should work once you have installed bugfixes
7 and 8, avaliable from
(From the GAP log you sent us, it seems that you have installed fixes
1-6). The reason why Kurt Ewald couldn't reproduce the problem is
that the bug was introduced in one of the fixes 4 to 6, and his
version of GAP is older.
Btw.: It might be a good idea to send bug reports to gap-trouble,
instead of the GAP forum, because (unless the bug produces wrong
results) are usually not of general interest.
