Solve the following python programming problem given the following code:
@ box (types.ClassInstanceType) 
def _box_class_instance(typ, val, c) : 
    (meminfo, dataptr) = cgutils.unpack_tuple (c.builder, val) 
    box_subclassed = _specialize_box (typ) 
    int_addr_boxcls = c.context.get_constant (types.uintp, id (box_subclassed)) 
    box_cls = c.builder.inttoptr (int_addr_boxcls, box.pyapi.pyobj) 
    box = c.pyapi.call_function_objargs (box_cls, ()) 
    llvoidptr = ir.IntType (8).as_pointer () 
    addr_meminfo = c.builder.bitcast (meminfo, llvoidptr) 
    addr_data = c.builder.bitcast (dataptr, llvoidptr) 
    def set_member(member_offset, value) : 
        offset = c.context.get_constant (types.uintp, member_offset) 
        ptr = cgutils.pointer_add (c.builder, box, offset) 
        casted = c.builder.bitcast (ptr, llvoidptr.as_pointer ()) 
        c.builder.store (value, casted) 
set_member (_box.box_meminfoptr_offset, addr_meminfo) 
    set_member (_box.box_dataptr_offset, addr_data) 
    return box 

    
    

    Fix the buggy line: box_cls = c.builder.inttoptr (int_addr_boxcls, box.pyapi.pyobj)

#Here is Python program to fix the buggy line: box_cls = c.

box_cls = c.builder.inttoptr (int_addr_boxcls, c.pyapi.pyobj)
