Description:
------------
The INIT_OVERLOADED_CLASS_ENTRY macro assumes that it's being passed a static string array for its class_name parameter. It obtains the length of the string with sizeof(), when it should be using strlen. This leads to class names being silently truncated when classes are initialized with a string variable instead of a static string array.

Reproduce code:
---------------
char* a = get_some_string();
zend_class_entry ce;
INIT_OVERLOADED_CLASS_ENTRY(ce, a, ...);

Expected result:
----------------
The name of the class in ce should be the return value of get_some_string()

Actual result:
--------------
The name of the class is truncated to sizeof(char*)-1 characters.
