    Bug #24778: Innodb: No result when using ORDER BY · f0fc4b88
    mhansson@dl145s.mysql.com authored
    This bug was intruduced by the fix for bug#17212 (in 4.1). It is not 
    ok to call test_if_skip_sort_order since this function will 
    alter the execution plan. By contract it is not ok to call 
    test_if_skip_sort_order in this context.
    
    This bug appears only in the case when the optimizer has chosen 
    an index for accessing a particular table but finds a covering 
    index that enables it to skip ORDER BY. This happens in 
    test_if_skip_sort_order.
