Comment 1 for bug 692211

Baron,

I cannot repeat the crash. This is what I get after starting with --innodb_auto_lru_dump=5 and no ib_lru_dump in the data dir:

$ ./mysqld --innodb_auto_lru_dump=5

Unfortunately, stack traces in the error log are useless for plugins, as addresses are not resolved. Can you run mysqld under gdb and get a gdb stack trace for the crash?
