            SUMMARY: UndefinedBehaviorSanitizer: float-cast-overflow /test/10.6_dbg_san/sql/sql_select.cc:31065:33

            Please note that this will be the last UBSAN error trace in the log, there will likely be other issues before it, like:

            UBSAN|applying zero offset to null pointer|storage/maria/ma_unique.c|_ma_unique_hash|maria_write|handler::ha_write_tmp_row|end_write

            Which is MDEV-35620.
