memcached.h
[+] struct memcached_st (1)

	Change	Effect
1	Type of field sasl has been changed from struct memcached_sasl_st* (4 bytes) to struct memcached_sasl_st (8 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.

Problems with Data Types, Low Severity (2)

memcached.h
[+] struct memcached_st (2)

	Change	Effect
1	Size of this type has been changed from 612 bytes to 616 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	The pointer level of field sasl has been decreased from 1 to 0.	The library functions will treat the value of this field as the lower-dimension array and will not read all elements. This may change the behavior of applications.
