+Summary: Mono seg fault on AppDomain.Unload
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+Mono seems to be seg faulting on AppDomain.Unload for some unknown reason.
+This code works perfectly on Windows using csc.
+
+Steps to reproduce the problem:
+Use the following code (maybe with some modification) to see the seg fault
+when loading a .dll file into an appdomain.
+
+  public void LoadPlugins() {
+    int i = 1;
+    AppDomain newDom = AppDomain.CreateDomain("Domain: " + i);
+
+    ComponentInterfaceFactory factory = (ComponentInterfaceFactory)
+newDom.CreateInstance("ICGComponent", "ComponentInterfaceFactory").Unwrap();
+
+    object[] constructArgs = null;
+    string file = "testComponent.dll";
+    ICGComponent aComponent = factory.Create(file, "testComponent",
+constructArgs);
+
+
+    // test execute
+    aComponent.Process();
+
+    Console.WriteLine("right before unload");
+    AppDomain.Unload(newDom);
+    Console.WriteLine("right after unload");
+  }
+
+A ComponentInterfaceFactory is a very simple class with one method which
+just returns an ICGComponent using Activator.CreateInstanceFrom.
+
+The testComponent class obviously inherits from the ICGComponent interface.
+
+Actual Results:
+[iseff@gates server]$ mono Main.exe
+hello from testComponent Constructor
+helllllo from testComponent!
+right before unload
+Segmentation fault
+
+
+Expected Results:
+[iseff@gates server]$ mono Main.exe
+hello from testComponent Constructor
+helllllo from testComponent!
+right before unload
+right after unload
+
+How often does this happen? 
+Every time.
