Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Type of field pad has been changed from uint32_t[7] (28 bytes) to uint32_t[5] (20 bytes).	Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
