+Summary: Invalid IL code with anonymous method/variable interaction
+
+I'm using Mono 1.1.7 built from source.  I get an "Invalid IL code" error
+when compiling and running the following:
+
+class X<T> {
+	public T eh;
+}
+
+static class Program {
+	delegate void D<T> (X<T> o);
+	static event D<bool> E;
+	
+	static void Main()
+	{
+		bool running = true;
+
+		E = delegate(X<bool> o) {
+			o.eh = false;
+			running = false;
+		};
+
+		X<bool> x = new X<bool>();
+		running = true;
+		E(x);
+		
+		while (running)
+			continue;
+	}
+}
+
+... which I compile with "gmcs crashcase.cs" and run with "mono crashcase.exe".
+
+$ mono crashcase.exe
+
+** ERROR **: Invalid IL code at IL0007 in Program:Main (): IL_0007: ldarg.0
+
+
+aborting...
+Aborted
+
+
+This error does not occur if I comment out either "o.eh = false;" or
+"running = false;" in the anonymous method.  (Or if I comment out both, of
+course.)
