Why can't assign script to object when class is in namespace and method uses default values

Question

Why i can't assign a script (c#) containing a namespace and a method with default values to a gameobject?

 // error: Can't add script behaviour Test. The scripts file name does not match the name of the class defined in the script!
 using UnityEngine;
 
 namespace Urks
 {
     public class Test : MonoBehaviour
     {
         public void TestMethod(int param = 5) {}
     }
 }
 
 // works
 using UnityEngine;
 
 namespace Urks
 {
     public class Test : MonoBehaviour
     {
         public void TestMethod(int param) {}
     }
 }
 
 // works
 using UnityEngine;
 
 public class Test : MonoBehaviour
 {
     public void TestMethod(int param = 5) {}
 }

Is there any hint? Can anybody reproduce this error?

The issue has been fixed on Windows, however the bug is still present on $$anonymous$$ac.

I just had this happen in 4.3.3f1. It was caused by having just the getter of a property inside a preprocessor block. If I removed the namespace it worked fine. If I moved the entire property in to the preprocessor it also worked fine; which is what I ended up doing.

I guess we should treat this error as a general clue to go looking for things like the use of preprocessor directives, attributes and other special use case items (for lack of a better description of these kinds of patterns). ...and of course by "go looking" I mean commenting stuff out until it works, and then bringing stuff back until it does not....
