+Summary: fail to save assembly or create reflection assembly with system librairies
+
+Description of Problem:
+I would like to modify "on the fly" some libraries, but Cecil fail to save
+or create reflection from system libraries
+
+Steps to reproduce the problem:
+
+Assembly b = Assembly.Load("System, Version=1.0.5000.0, Culture=neutral,
+PublicKeyToken=b77a5c561934e089");
+AssemblyDefinition assembly = AssemblyFactory.GetAssembly(b.Location);
+
+AssemblyFactory.SaveAssembly(assembly, "./test.dll");
+//AssemblyFactory.CreateReflectionAssembly(assembly);
+
+
+Actual Results:
+
+Unhandled Exception: System.OverflowException: Number overflow.
+in <0x00000> <unknown method>

+(Mono.Cecil.AssemblyDefinition asm, System.String file)
+in <0x0004d> TestCecil.CMain:Main (System.String[] args)
+
+
+Expected Results:
+  a new test.dll in local directory, copy of System.dll
+
+How often does this happen? 
+  Always
+
+Additional Information:
+  the problem is in the function
+Mono.Cecil.MetaData.MetaDataWriter::GetStrongNameSignatureSize (), the size
+value is lower than 32
