If the "fake_big_file" command fails, be sure to close the file before returning. (CVS 801) (check-in: fa1b5e2119 user: drh tags: trunk)

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) (check-in: f04547edfa user: drh tags: trunk)
