Seems it not just an issue with Memory buffers:

The following program compiles and runs on .NET but crashes on mono


using System;
using System.Drawing;
using System.Windows.Forms;

public class MyForm : Form
{
    [STAThreadAttribute()]
    static void Main()
    {
        Application.Run(new MyForm());
    }



    protected override void OnPaint(PaintEventArgs e)
    {

        // Get handle to device context.
        IntPtr hdc = e.Graphics.GetHdc();
        Graphics newGraphics = Graphics.FromHdc(hdc);
        Graphics newGraphics2 = Graphics.FromHdc(newGraphics.GetHdc());        
        newGraphics2.Dispose();
        newGraphics.Dispose();
    }

}
