+Summary: getting proxy for ContextBoundObject with virtual generic functions fails
+
+When object derived from ContextBoundObject contains virtual generic
+function (or derive from interface with such function) is created, runtime
+throws exception in native code.
+
+1. Compile this code:
+
+class C : System.ContextBoundObject
+{
+ public virtual T Q<T> (T t)
+ {
+ return t;
+ }
+
+ public static void Main ()
+ {
+ new C ();
+ }
+}
+
+2. Run compiled program
+
+Actual Results:
+
+
+
+** (./foo.exe:18282): WARNING **: type 0x1e not handled
+
+** ERROR **: file marshal.c: line 3347 (mono_mb_emit_restore_result):
+should not be reached
+aborting...
