When trying to use a const string as the default value for a property, it generates invalid C (referencing _tmpN variables which were not declared).


nemequ@desktop:~/t$ cat test.vala
public const string BAR = "Doesn't!\n";
public const string BAZ = "Works!\n";

public class Foo : GLib.Object {
  public string a { get; set; default = "Works!\n"; }
  public string b = "Works!\n";
  public string c { get; set; default = BAR; }
  public string d = BAR;
  public string e;

  construct {
    this.e = BAZ;
  }
}

static int main(string[] args) {
  var foo = new Foo();
  GLib.stderr.printf(foo.a);
  GLib.stderr.printf(foo.b);
  GLib.stderr.printf(foo.c);
  GLib.stderr.printf(foo.d);
  GLib.stderr.printf(foo.e);
  return 0;
}
