Assume we have the following weak message send:

message := WeakMessageSend��
�� receiver: Morph new
�� selector: #color.
100000 timesRepeat: [ message value ]

If you execute it in latest Pharo and VM ��you will (almost 100% sure) get DNU. (but it should just return nil if receiver is garbage collected)

How can I ensure that it selector is not being sent to nil?

Am I doing something wrong?

Cheers,

Alex
