Hi, I guess is as a bug in ALTER TABLE with MySQL 4.1,compiled from BK TREE on 2003-01-22. Table schema : CREATE TABLE cmdlivrare(IDCMD INT(9) NOT NULL PRIMARY KEY DEFAULT 2000,mUser CHAR(16),Dep CHAR(4),IDCLI INT(16),FactExt CHAR(20),LivrFinish SMALLINT(1),DataIntro DATE,DataIese DATE,INDEX(Dep),INDEX(FactExt),INDEX(IDCLI),INDEX(mUser),INDEX(LivrFinish),I NDEX(DataIntro),INDEX(DataIese));
I wish to alter this table and modify the definition of IDCMD to "IDCMD INT(9) AUTO_INCREMENT NOT NULL PRIMARY KEY DEFAULT 30000" For this i do : alter table cmdlivrare modify IDCMD INT(9) AUTO_INCREMENT NOT NULL PRIMARY KEY DEFAULT 30000; MySQL daemon got signal 11. MySQL log "said": ============================================================================ ================================= mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=402653184 read_buffer_size=2093056 sort_buffer_size=2097144 max_used_connections=0 max_connections=100 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 802415 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x865b0a0 Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... Cannot determine thread, fp=0xbe7fd6f8, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x8114078 0x40039951 0x816785a 0x8167167 0x81807ac 0x8182370 0x8121257 0x8124c45 0x811f8a7 0x811f4fe 0x811ee79 0x4003376e 0x402687da New value of fp=(nil) failed sanity check, terminating stack trace! Please read http://www.mysql.com/doc/U/s/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved stack trace is much more helpful in diagnosing the problem, so please do resolve it Trying to get some variables. Some pointers may be invalid and cause the dump to abort... thd->query at 0x865e3c8 = alter table cmdlivrare modify IDCMD INT(9) AUTO_INCREMENT NOT NULL PRIMARY KEY DEFAULT 30000 thd->thread_id=1 Successfully dumped variables, if you ran with --log, take a look at the details of what thread 1 did to cause the crash. In some cases of really bad corruption, the values shown above may be invalid. The manual page at http://www.mysql.com/doc/C/r/Crashing.html contains information that should help you find out what is causing the crash. ============================================================================ ================================= resolve_stack_dump succesfully does : 0x8114078 handle_segfault + 416 0x40039951 _end + 936099857 0x816785a _Z11pack_fieldsiR4ListI12create_fieldE + 170 0x8167167 _Z16rea_create_tableP3THDPcP24st_ha_create_informationR4ListI12create_fieldE jP6st_key + 883 0x81807ac _Z18mysql_create_tableP3THDPKcS2_P24st_ha_create_informationR4ListI12create_ fieldERS5_I3KeyEbbj + 2500 0x8182370 _Z17mysql_alter_tableP3THDPcS1_P24st_ha_create_informationP13st_table_listR4 ListI12create_fieldERS6_I3KeyERS6_I10Alter_dropERS6 + 2736 0x8121257 _Z21mysql_execute_commandP3THD + 2803 0x8124c45 _Z11mysql_parseP3THDPcj + 221 0x811f8a7 _Z16dispatch_command19enum_server_commandP3THDPcj + 879 0x811f4fe _Z10do_commandP3THD + 110 0x811ee79 handle_one_connection + 813 0x4003376e _end + 936074798 0x402687da _end + 938389146 I has the bad inspiration to compile without debug option.I try to recompile now and i will try to study to see what happened.
