e7e8bc7739 Take care not to modify the sqlite* pointer to sqlite_exec() if we suspect 
that the pointer is stale - that it has previously been passed to
sqlite_close().  Possible fix for ticket #202.  Prior to this fix, test
misuse-5.3 was causing a change to a buffer that had been previously free()-ed. (CVS 799)
