[Vm-dev] New case to crash Spur VM

[Denis Kudriashov]

I found automated way how to check problem:

p := [ Object basicSize ] fork.
p suspend.

3 timesRepeat: [p step: p suspendedContext].
newContext := p completeStep: p suspendedContext.
newContext selector. "=> doesNotUnderstand:"
newContext arguments first selector == 0
