Bug in the example code in the manual: The __copyinit__ and __moveinit__ special methods

[abhinav-upadhyay]

Bug Description

The example code is:

struct MyString:
    var data: Pointer[Int8]

    # StringRef has a data + length field
    def __init__(self&, input: StringRef):
        let data = Pointer[Int8].alloc(input.length+1)
        data.memcpy(first.data, input.length)
        data[input.length] = 0
        self.data = Pointer[Int8](data)

    def __del__(owned self):
        self.data.free()

The following line is wrong:

        data.memcpy(first.data, input.length)

should have been

        data.memcpy(input.data, input.length)
