Perhaps I was using a custom vm, sorry for that confusion.  Currently, we have
a bug in 3.7b, which is becomeForward:copyHash: results in a primitive failure.
 There are two parts for this to work, the image changes that call the new
method and the new primitive.

This part says that the VM change was introduced in the VMMaker3-7a.sar
package.

approved for 3.7a:

closed:

and added to the update stream as update 5578:

at which thought it would perpetuate forward and was very happy.

What must be done to get this into the latest VM?

Thank you very much,
