Hi. At the end of test_if_skip_sort_order() you put (in 5.3): 17959 /* 17960 orig_cond is a part of pre_idx_push_cond, 17961 no need to restore it. 17962 */ 17963 orig_cond= 0; 17964 orig_cond_saved= false; 17965 if (orig_cond_saved && !changed_key) 17966 tab->set_cond(orig_cond); Besides incorrect indentation, you set orig_cond_saved to false, and in the next line writes an if() statement that can only work if orig_cond_saved is true. If orig_cond_saved=false is correct, then this if() can be completely removed. Or, may be, orig_cond_saved should not be set to false? Regards, Sergei
