CogVM crash

 
  The VM ('Croquet Closure Cog VM [CoInterpreter
VMMaker.oscog-eem.128] Croquet Cog 4.0.0') just crashed on me on MacOS
X.  I tried to reproduce the same sequence but did not happen.

  The image is 4.1 derived.  The stack dump seems to be related to
making uniclasses and recompilation.
