    write and execute permission, but without read permission, to serve as temporary
    directories.  Apply this same standard to the "." fallback directory.
<p><b>Bug Fixes:</b>
<li>Fix a problem with the multi-row one-pass DELETE optimization that was
    causing it to compute incorrect answers with a self-referential subquery in
    the WHERE clause.  Fix for ticket
    [https://www.sqlite.org/src/info/dc6ebeda9396087|dc6ebeda9396087]





<li>When checking for the WHERE-clause push-down optimization, verify that all terms
    of the compound inner SELECT are non-aggregate, not just the last term. Fix for ticket
    [https://www.sqlite.org/src/info/f7f8c97e97597|f7f8c97e97597].
<li>Fix a locking race condition in Windows that can occur when two or more processes
    attempt to recover the same [hot journal] at the same time.

<li>Fix a possible segfault with DELETE when table is a [rowid table] with an 
    [INTEGER PRIMARY KEY] and the WHERE clause contains a OR and
    the table has one or more indexes that are able to trigger the OR optimization,
    but none of the indexes reference any table columns other than the INTEGER PRIMARY KEY.
