+# Bug #25843 Changing default database between PREPARE and EXECUTE of statement
+# breaks binlog.
+#
+# There were actually two problems discovered by this bug:
+#
+#   1. Default (current) database is not fixed at the creation time.
+#      That leads to wrong output of DATABASE() function.
+#
+#   2. Database attributes (@@collation_database) are not fixed at the creation
+#      time. That leads to wrong resultset.
+#
+# Binlog breakage and Query Cache wrong output happened because of the first
+# problem.
