2 File IO Questions (Phobos)

[Zane]

Hello all,

I have been looking at Phobos lately, and currently I am having some trouble 
understanding what is going on with the following 2 trivial examples.  First of 
all, I am using dmd v1.050.

This one prints "[‼   This is some stuff!]".  Where do the 4 prepended 
bytes come from?
(1) ---------------------------------------------------------------->

import std.stream;
import std.stdio;

int main()
{
        char[] stuff = "This is some stuff!";

        File f = new File("stuff.txt", FileMode.Out | FileMode.In);
        f.write(stuff);
        f.seekSet(0);
        stuff = f.readLine();
        writef("[%s]", stuff);
        f.close;

        return 0;
}


This one I wanted to have a class open a file upon initialization of an 
instance, and close a file when the destructor is called.  I get an "Error: 
Access Violation" unless I comment out the file.close line.  Why?  (of course 
this example also has the same problem as the first example, but I kept the 
first one simpler to narrow down things)
(2) ---------------------------------------------------------------->

import std.stream;

public class StuffWriter
{
        File file;

        this(char[] filename)
        {
                file = new File(filename, FileMode.Out);
        }

        ~this()
        {
                file.close; //this causes an access violation???
        }

        public void write(char[] stuff)
        {
                file.write(stuff);
        }
}

int main()
{
        StuffWriter sw = new StuffWriter("stuff.txt");
        sw.write("This is some stuff!");

        return 0;
}


Thanks!
