- mysql-test-run.pl --valgrind complains when all tests succeed. - perfschema.all_instances fail on non-linux, where ENABLE_TEMP_POOL is not set and therefore BITMAP mutex is not used. - MDEV-132: main.mysqldump fails because it depends on exact size of stdio buffers. - MDEV-99: rpl.rpl_cant_read_event_incident fails due to a race where the slave manages to connect while the test case is in the middle of setting up the master, causing the slave to replicate extra/wrong events. - MDEV-133: rpl.rpl_rotate_purge_deadlock fails because it issues a DEBUG_SYNC SIGNAL immediately followed by RESET; this means that sometimes the intended receipient has no time to see the signal before it is cleared by the RESET, causing wait to timeout.

# Testing that execution of two concurrent INSERTing connections both
|
|
# triggering the binlog rotation is correct even though their execution
|
|
# is interleaved.
|
|
# The test makes the first connection to complete the rotation part
|
|
# and yields control to the second connection that rotates as well and
|
|
# gets first on purging. And the fact of interleaving does not create
|
|
# any issue.
