+For the record:
+This is caused by the fact that mono_type_get_underlying_type () returns
+a MonoType for GENERICINST types whose data.klass field points to
+the 'generic' generic class, not the 'specific' generic class created
+by mono_class_create_generic (). So either
+mono_type_get_underlying_type () needs to return the 'specific'
+generic class (and the byval_arg
+field of this class needs to point to itself and not to the generic
+class), or the code calling get_underlying_type () needs to call
+mono_class_from_mono_type () instead of accessing type->data.klass
+directly. There are lots of places inside the runtime where this
+bug manifests itself. For example, 
+is caused by the same problem.
