5c327dbb46 http://www.sqlite.org/cvstrac/tktview?tn=2046 
The virtual table interface allows for a cursor to field multiple
xFilter() calls.  For instance, if a join is done with a virtual
table, there could be a call for each row which potentially matches.
Unfortunately, fulltextFilter() assumes that it has a fresh cursor,
and overwrites a prepared statement and a malloc'ed pointer, resulting
in unfinalized statements and a memory leak.

This change hacks the code to manually clean up offending items in
fulltextFilter(), emphasis on "hacks", since it's a fragile fix
insofar as future additions to fulltext_cursor could continue to have
the problem. (CVS 3521)

debbcdfead Require a minimum fanout for interior nodes. This prevents cases 
where excessively large terms keep the tree from finding a single
root.  A downside is that this could result in large interior nodes in
the presence of large terms, which may be prone to fragmentation,
though if the nodes were smaller that would translate into more levels
in the tree, which would also have that problem. (CVS 3510)
