innodb.innodb_bug56680 w4 [ fail ]
Test ended at 2011-12-16 21:38:49

111216 13:38:48 InnoDB: Assertion failure in thread 2895530864 in file buf0flu.c line 1195
InnoDB: Failing assertion: buf_block_get_state(block) == BUF_BLOCK_FILE_PAGE

Trying 'gdb' to get a backtrace
Guessing that core was generated by '/home/jenkins/workspace/percona-server-5.5-param/BUILD_TYPE/debug/Host/centos6-32/Percona-Server-5.5.18-rel21.0/sql/mysqld'
Output from gdb follows. The first stack trace is from the failing thread.
The following stack traces are from all threads (so the failing one is
duplicated).
