would incorrectly prepare to compare a NULL column prefix in a
secondary index with a non-NULL column in a clustered index.
InnoDB: An incorrect purge would occur when rolling back an update to a delete-marked record. (Bug #17302896)

Rolling back an
INSERT after a
BLOB write would result in
an assertion failure. The assertion has been modified to allow
BLOB pointers if an error
occurs during a
srv_master_thread background thread,
which monitors server activity and performs activities such as
page flushing when the server is inactive or in a shutdown
state, runs on a one second delay loop.
srv_master_thread would fail to check if the
server is in a shutdown state before sleeping.

An infinite loop could occur in
buf_page_get_gen when handling
(Bug #12560151, Bug #61132)
Within a stored program, comparison of the value of a scalar
subquery with an
IN clause resulted in an
error for the first execution and raised an assertion for the
my_strtoll10() function could incorrectly
convert some long string-format numbers to numeric values and
fail to set the overflow flag.
For queries that accessed an
INFORMATION_SCHEMA table in a subquery, an
attempt to lock a mutex that had already been locked could cause
a server crash.
DIV expressions, assignment of
the result to multiple variables could cause a server crash.
