+
+The runtime aborts because
+
+TypeBuilder lTypeBuilder = lModuleBuilder.DefineType("Dummy." +
+lAssemblyName.Name, lAttributes, null);
+
+defines a class that doesn't extend any type. This leads to
+a non-verifiable assembly.
+
+If the line is changed to
+
+TypeBuilder lTypeBuilder = lModuleBuilder.DefineType("Dummy." +
+lAssemblyName.Name, lAttributes);
+
+the generated assembly is OK.
+
+MS.NET seems to catch null base types, as the attached patch does.
