+Summary: Invalid assignment causes compiler to crash.
+
+The following code makes the compiler die with an exception:
+
+class Foo {
+	struct myStruct {
+		bool foo;
+	}
+
+	private void breakMe ()
+	{
+		myStruct = new myStruct ();
+	}
+}
+
+When compiled with MCS, I get:
+
+Exception caught by the compiler while compiling:
+   Block that caused the problem begin at: test.cs: (6)
+                     Block being compiled: [test.cs: (7),test.cs: (9)]
+
+Unhandled Exception: System.InvalidCastException: Cannot cast from source
+type to destination type

+
+I this only happens with structs, but not with classes.  If I replace
+"struct" with "class" I get what I expected, i.e.:
+
+test.cs(8) error CS0131: Left hand of an assignment must be a variable, a
+property or an indexer
