When an index is used by all branches of the WHERE_MULTI_OR optimization and
becomes a covering index, make sure the index has been created prior to
NULLing it in the OP_NullRow opcode of a LEFT JOIN. See
[forum:/forumpost/0575376e07|forum post 0575376e07]. The covering-index for
WHERE_MULTI_OR optimization was added by [62678be3df35cdcb]. Test cases are
in the orindex01.test module of TH3.
