The bug happened because in some cases the function JOIN::exec did not save the value of TABLE::pre_idx_push_select_cond in TABLE::select->pre_idx_push_select_cond for the sort table. Noticed and fixed a bug in the function make_cond_remainder that builds the remainder condition after extraction of an index pushdown condition from the where condition. The code erroneously assumed that the function make_cond_for_table left the value of ICP_COND_USES_INDEX_ONLY in sub-condition markers. Adjusted many result files from the regression test suite after this fix .
