Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Medium Severity (8)

	Change	Effect
1	Field _shard has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

3	Field maxConns has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
4	Field pidFile has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
5	Type of field keyFile has been changed from bool (1 byte) to std::string (4 bytes).	This field may be incorrectly initialized or accessed by applications.

	Change	Effect
1	Virtual method DBClientWithCommands::ensureIndex ( std::string const&, BSONObj, bool, std::string const&, bool, bool, int, int ) has been added to this class instead of DBClientWithCommands::ensureIndex ( std::string const&, BSONObj, bool, std::string const&, bool, bool, int ).	Applications will pass parameters of older replaced method to newly added virtual method. This may result in crash or incorrect behavior of applications.

	Change	Effect
1	Virtual method SocketException::server ( ) const has been added to this class.	The layout of v-table has been changed. This leaf class has no exported constructors and therefore applications will copy an old v-table of the class that will not contain a pointer to added virtual method. Call of any method in this class may result in crash or incorrect behavior of applications. NOTE: if new virtual method is called only from other new methods, then binary compatibility should not be affected.
