Topic: innodb-plugin, mysql-5.1.42 and EL4

Hello,

The RHEL4 i386 version of MySQL 5.1.42 in the repo seems to have some problems with innodb-plugin. I tried enabling innodb-plugin on a CentOS 4.8 box (with the latest updates) and it dies at startup with:

100116 10:39:51 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
100116 10:39:51 [Note] Plugin 'ndbcluster' is disabled.
100116 10:39:51 - 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=134217728
read_buffer_size=16777216
max_used_connections=0
max_threads=400
threads_connected=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 657900 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

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...
stack_bottom = (nil) thread_stack 0x30000

The manual page at http://dev.mysql.com/doc/mysql/en/c... contains
information that should help you find out what is causing the crash.

The server is one of the nodes of a two-master replication setup and it starts up fine without innodb-plugin. The plugin was started using:

ignore-builtin-innodb
plugin-load=innodb=ha_innodb_plugin.so;innodb_trx=ha_innodb_plugin.so;innodb_locks=ha_innodb_plugin.so;innodb_cmp=ha_innodb_plugin.so;innodb_cmp_reset=ha_innodb_plugin.so;innodb_cmpmem=ha_innodb_plugin.so;innodb_cmpmem_reset=ha_innodb_plugin.so
innodb_file_per_table=1
innodb_file_format=barracuda

There are several existing (regular) InnoDB databases.

I've also tried the same steps on a CentOS 5.4 x86_64 box with the same MySQL version installed, same config and also with a couple of existing InnoDB databases, the daemon starts fine with innodb-plugin.

Any ideas or suggestions would be greatly appreciated. Thanks.
