Yes. I yesterday downloaded XCode and built the Mac VM, only to find 
that it throws a clear error (LargeNegativeInteger is not compact at 5, 
can't continue) to the console. I told this to Eliot, but forgot to say 
it in the lists. I apologize. Anyway, for some reason, the win vm you 
posted, instead of giving the error and exiting cleanly, it does an 
invalid access and is terminated. Maybe you want to check that.

BTW, most console messages (i.e. stdout) will be missed in these days of 
graphical shells. An OS dialog would be better.

Thank Eliot, you and Teleplace for this great gift! This is a major 
milestone in the history of Squeak.
