The following piece of code compiles without error on D1(1.072)
D2(2.057).
However the D2 version doesn't run fine. ( output below )

* Output of the D1 version :
receiver 1 :Hey
receiver 2 :Hey
receiver 1 :Hey
* Output of the D2 version :
receiver 1 :
receiver 2 :
receiver 1 :
Is this a bug or something stupid on my part ?
