Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Type of field result has been changed from struct memcached_result_st (304 bytes) to memcached_result_st (312 bytes).	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

	Change	Effect
1	Field numeric_value 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.
