Welcome back big testcase :-)

> XXX bfdtab->count=1751 table->nbuckets=524288
> XXX bfdtab->count=1752 table->nbuckets=0

So, something between those two wants to reallocate the hash table to have
more buckets than can fit into an uint.  Like in that other bug report, maybe
also print the sizes of sections or the number of presumed entries that it
wants to maximally add to get a feel for how much this is overestimating stuff.

(E.g. in sec_merge_maybe_resize to print the 'added' param from inside the
if condition there; or sec->size in the sole caller of that function)

It may be that this is again a too aggressive overestimation.  But it may also
be real, in which case we really need to audit the code paths that are supposed
to handle the cannot-enlarge-hashtable-anymore case (what essentially is
supposed
to happen is that these overly large input sections simply aren't deduplicated
but pasted into the output as is; obviously something goes wrong for that to
happen).
