+Summary: mcs 0.24 compile exception relating to foreach loop
+
+Trying out the .24 build I got an error tring to compile a file that 
+worked fine in .23.
+
+Here is the exception seen:
+
+C:\src\Dataphor\Base>mcs *.cs
+Exception caught by the compiler while compiling:
+   Block that caused the problem begin at: .\Base.cs: (339)
+                     Block being compiled: [Internal: (1),Internal: (1)]
+
+Unhandled Exception: System.NotSupportedException: The invoked member is 
+not supported in a dynamic module.

+I'll attach the base.cs but you won't be able to compile it without the 
+rest of the project.  Hopefully you will be able to diagnose the problem 
+from the call stack above and by looking at the specific lines of code 
+that are tring to be compiled.  If you can give me an idea of what the 
+problem might be I can spend the time to try to create a simple test case.
+
+I'm guessing it's releated to the iterator changes that went in.
+
+Here is the code that is causing the error.
+
+        protected object RecurseChildren(IParent AParent, ref int AIndex)
+        {
+            object LReturnObject = null;
+            foreach (object LChild in AParent.Children)
+            {
+                if (FType.IsInstanceOfType(LChild) || LChild.GetType
+().IsSubclassOf(FType))
+                {
+                    AIndex--;
+                    if (AIndex < 0)
+                    {
+                        LReturnObject = (LChild);
+                        break;
+                    }
+                }
+                if (LChild is IParent)
+                {
+                    LReturnObject = RecurseChildren((IParent)LChild, ref 
+AIndex);
+                    if (LReturnObject != null)
+                        break;
+                }
+            }
+            return LReturnObject;
+        }
