Hello,
I am using a new 64bit vm on Windows (Stack Spur Apr 12 2017) with a mostly
up to date trunk image (last update: #17172), and when trying to open the
Objects morph (to pull in objects for Morphic), I get an error in
KedemaMorph:

calcTurtlesCount

turtleCount := 0.
turtlesDict do: [:a | turtleCount := turtleCount + a size].

Smalltalk vmParameterAt: 5 put: ((turtleCount * 3) min: 16000 max: 4000).
Smalltalk vmParameterAt: 6 put: ((turtleCount * 6) min: 32000 max: 8000).

The vmParamterAt: 5 put: xxxx (4000 in my case), gets a primitive failure.

Thanks,
cbc
