Elena Stepanova added a comment - 2019-01-04 12:37 I have a bunch of non-simplified non-deterministic MTR tests which cause all kinds of crashes and failures by simply re-running over and over. But with ASAN, they all produce the same error reported here, so I cannot get any further with them – maybe they all are a result of this initial problem, or maybe they are independent. Below are a non-exhaustive list of failures that I've got on 10.4 3bdd93c10 non-ASAN debug build. 190103 8:09:49 [ERROR] mysqld got signal 11 ;   #3 <signal handler called> #4 0x000056498ae20aee in remove_from_used_mutex (locked_mutex=0xa5a5a5a5a5a5a5a5, mutex=0x7f147c03be80) at /data/src/10.4/mysys/thr_mutex.c:796 #5 0x000056498adf15b1 in my_hash_iterate (hash=0x7f147c0d9e30, action=0x56498ae20a76 <remove_from_used_mutex>, argument=0x7f147c03be80) at /data/src/10.4/mysys/hash.c:796 #6 0x000056498ae2071b in safe_mutex_free_deadlock_data (mp=0x7f147c03be80) at /data/src/10.4/mysys/thr_mutex.c:660 #7 0x000056498ae20619 in safe_mutex_destroy (mp=0x7f147c03be80, file=0x56498b294390 "/data/src/10.4/mysys/thr_lock.c", line=464) at /data/src/10.4/mysys/thr_mutex.c:604 #8 0x000056498ae1c732 in inline_mysql_mutex_destroy (that=0x7f147c03be80, src_file=0x56498b294390 "/data/src/10.4/mysys/thr_lock.c", src_line=464) at /data/src/10.4/include/mysql/psi/mysql _thread.h:669 #9 0x000056498ae1cd21 in thr_lock_delete (lock=0x7f147c03be68) at /data/src/10.4/mysys/thr_lock.c:464 #10 0x000056498ad6c010 in mi_close (info=0x7f147c185390) at /data/src/10.4/storage/myisam/mi_close.c:104 #11 0x000056498ad54ee2 in ha_myisam::close (this=0x7f147c1e5218) at /data/src/10.4/storage/myisam/ha_myisam.cc:932 #12 0x000056498a6651fe in handler::ha_close (this=0x7f147c1e5218) at /data/src/10.4/sql/handler.cc:2786 #13 0x000056498a465d03 in closefrm (table=0x7f147c10fd60) at /data/src/10.4/sql/table.cc:3609 #14 0x000056498a58b370 in intern_close_table (table=0x7f147c10fd60) at /data/src/10.4/sql/table_cache.cc:222 #15 0x000056498a58b778 in tc_purge (mark_flushed=false) at /data/src/10.4/sql/table_cache.cc:335 #16 0x000056498a2b40ee in purge_tables (purge_flag=false) at /data/src/10.4/sql/sql_base.cc:331 #17 0x000056498a2b4208 in close_cached_tables (thd=0x7f147c000b00, tables=0x0, wait_for_refresh=true, timeout=2) at /data/src/10.4/sql/sql_base.cc:360 #18 0x000056498a4ecafd in reload_acl_and_cache (thd=0x7f147c000b00, options=4, tables=0x0, write_to_binlog=0x7f14f8226030) at /data/src/10.4/sql/sql_reload.cc:339 #19 0x000056498a354e18 in mysql_execute_command (thd=0x7f147c000b00) at /data/src/10.4/sql/sql_parse.cc:5639 #20 0x000056498a35c244 in mysql_parse (thd=0x7f147c000b00, rawbuf=0x7f147c02a058 "FLUSH TABLES /* QNO 17941 CON_ID 17 */", length=38, parser_state=0x7f14f8226650, is_com_multi=false, is_nex t_command=false) at /data/src/10.4/sql/sql_parse.cc:8104 #21 0x000056498a34946e in dispatch_command (command=COM_QUERY, thd=0x7f147c000b00, packet=0x7f147c00b421 "FLUSH TABLES /* QNO 17941 CON_ID 17 */", packet_length=38, is_com_multi=false, is_n ext_command=false) at /data/src/10.4/sql/sql_parse.cc:1851 #22 0x000056498a347e92 in do_command (thd=0x7f147c000b00) at /data/src/10.4/sql/sql_parse.cc:1396 #23 0x000056498a4b40ba in do_handle_one_connection (connect=0x56498e3abf20) at /data/src/10.4/sql/sql_connect.cc:1402 #24 0x000056498a4b3e3e in handle_one_connection (arg=0x56498e3abf20) at /data/src/10.4/sql/sql_connect.cc:1308 #25 0x00007f14fb5a6494 in start_thread (arg=0x7f14f8227700) at pthread_create.c:333 #26 0x00007f14f9ba793f in clone () from /lib/x86_64-linux-gnu/libc.so.6   Query (0x7f147c02a058): FLUSH TABLES /* QNO 17941 CON_ID 17 */ Connection ID (thread ID): 13 Status: NOT_KILLED (^ Similar to MDEV-6524 closed as not reproducible) Error: Freeing overrun buffer 0x7f88b81a9fd0 at mysys/safemalloc.c:194, mysys/my_malloc.c:223, sql/sql_sequence.h:150, sql/sql_class.cc:117, mysys/hash.c:128, mysys/hash.c:151, sql/sql_class.cc:1509, sql/mysqld.cc:2804 190103 0:57:56 [ERROR] mysqld got signal 11 ;

Alexander Barkov added a comment - 2019-01-15 07:01 When performing an ALTER for a temporary table, TABLE_SHARE::orig_table_name is copied from the old table in this line: new_table->s->orig_table_name= table->s->table_name.str; But the old table is then deleted in this line: /* Remove link to old table and rename the new one */ thd->drop_temporary_table(table, NULL, true ); with this stack: #0 __memset_sse2 () at ../sysdeps/x86_64/memset.S:81 #1 0x0000000001225d9f in free_memory (ptr=0x7ffe60095200) at /home/bar/maria-git/server.10.4/mysys/safemalloc.c:278 #2 0x0000000001225a60 in sf_free (ptr=0x7ffe60095200) at /home/bar/maria-git/server.10.4/mysys/safemalloc.c:197 #3 0x0000000001213aa4 in my_free (ptr=0x7ffe60095200) at /home/bar/maria-git/server.10.4/mysys/my_malloc.c:221 #4 0x00000000009ca5d7 in THD::free_tmp_table_share (this=0x7ffe60000b00, share=0x7ffe60095200, delete_table=true) at /home/bar/maria-git/server.10.4/sql/temporary_tables.cc:1446 #5 0x00000000009c8919 in THD::drop_temporary_table (this=0x7ffe60000b00, table=0x7ffe600965c0, is_trans=0x0, delete_table=true) at /home/bar/maria-git/server.10.4/sql/temporary_tables.cc:646 #6 0x0000000000870b7c in mysql_alter_table (thd=0x7ffe60000b00, new_db=0x7ffe600051e0, new_name=0x7ffe600055b0, create_info=0x7ffff0bd4210, table_list=0x7ffe60015d08, alter_info=0x7ffff0bd4150, order_num=0, order=0x0, ignore=false) After this, TABLE_SHARE::orig_table_name of the new (altered) table points to the old freed name.
