Problems with Data Types, High Severity (1)

memcached.h
[+] struct memcached_st (1)

	Change	Effect
1	Field connected has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
