bsonobjbuilder.h
namespace mongo
[+] class BSONObjBuilder (1)

	Change	Effect
1	Size of this class has been changed from 52 bytes to 56 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.

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field sslCipherConfig 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.

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Size of this global data has been changed from 36 bytes to 40 bytes.	Applications will obtain a different value and execution may change.
