This sounds similar to a problem that I saw some time ago. I would
get a coredump in one of the hash functions. The coredump showed
that two buckets had been "joined." The beginning entries in
the list were all in the right bucket, but at some point the hash
values didn't match.
If I recall correctly, it turned out to be a bug with the filemap
routines stomping on memory out of bounds. I found it finally by
noticing that one of the hash_link pointers was wrong by just one
bit.
