	Change	Effect
1	Type of return value has been changed from int (4 bytes) to xcb_get_property_cookie_t (4 bytes).	1) The return value became passed in memory as the hidden first argument (address of the space on the stack provided by the caller) instead of the register and therefore the layout of parameter's stack has been shifted by 4 bytes. All the parameters will be incorrectly initialized by applications. 2) Applications will read the wrong memory block instead of the return value.
