Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field object_size 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.
