Valgrind Problems for Innodb

[Brian Aker]

MySQL reference for bug -> http://bugs.mysql.com/bug.php?id=44186

We are seeing a lot of messages like this in the current plugin:
==23993== Conditional jump or move depends on uninitialised value(s)
==23993== at 0x66BB80: rw_lock_x_lock_func (sync0rw.ic:292)
==23993== by 0x6188C2: log_group_checkpoint (log0log.c:1782)

(storage_engine.cc:205)
==23993== by 0x5078F8: _ZL17plugin_initializeP13st_plugin_int (sql_plugin.cc:599)
==23993== by 0x5094D7: plugin_init(int*, char**, int) (sql_plugin.cc:708)
==23993== by 0x4168B0: main (drizzled.cc:1562)

This can be seen by just starting the Drizzle daemon binary up in valgrind and then shutting it down.

Hi!

I believe there is a similar bug on this for MySQL right now. This bug
is in the Innodb plugin.

Cheers,

You can't grep a dead tree.

moving out of aloha, since this is an issue in innodb plugin

I can't reproduce this in latest truck, is it still valid?
