When defining a property for a class default should not be used if the getter and setter are defined. An error should probably be emitted. Currently it just prints:

** (valac-0.18:32211): CRITICAL **: vala_code_node_replace_expression: assertion `self != NULL' failed


Below is a simple test case that can be run.


namespace Error
{
   public struct A
   {
      public int val
      { get; set; }
 
      public A()
      {
         val = 55;
      }
   }
 
   public class B : Object
   {
      private A backing_a;
 
      // BUG: This is the error area. It works if I have:
      // public A foo
      // { get; set; default = A(); }
      // It does not work the below way and needs to emit an error message.
      public A foo
      {
         get
         {
            return backing_a;
         }
 
         set
         {
            backing_a = value;
         }
 
         default = A();
      }
 
      public B()
      {
      }
   }
 
   public static void main(string[] args)
   {
      B temp;
 
      temp = new B();
      stdout.printf("Value: %d\n", temp.foo.val);
   }
}
