Problems with Data Types, High Severity (2)

dbclient.h
namespace mongo
[+] class DBClientConnection (1)

	Change	Effect
1	Size of this class has been changed from 112 bytes to 116 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. 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.

message.h
namespace mongo
[+] class MessagingPort (1)

	Change	Effect
1	Size of this class has been increased from 156 bytes to 160 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.
