How to simulate a corrupt state exception in .NET 4?

Question

Well, in .NET 4 Microsoft added the HandleProcessCorruptedStateExceptions attribute:

HandleProcessCorruptedStateExceptionsAttribute Class

I want to test this feature. How can I bring my application to a "corrupt state"?

Screwing up the garbage collected heap is always a good way:

using System;
using System.Runtime.InteropServices;


class Program {
  unsafe static void Main(string[] args) {
    var obj = new byte[1];
    var pin = GCHandle.Alloc(obj, GCHandleType.Pinned);
    byte* p = (byte*)pin.AddrOfPinnedObject();
    for (int ix = 0; ix < 256; ++ix) *p-- = 0;
    GC.Collect();   // kaboom
  }
}
