Hi,

The swapping out a class that has instances does not work. More precisely, it crashes the image when loading back.

What a hacky guy you are ;)
I discover that it fails even before...Implement this in ClassProxy:

hello
     Transcript show: 'Hello'

Then evaluate:

o := MyObject new.
o foo: 123.
p := ClassProxy new.
p become: MyObject.
o hello.

and the vm will crash and nothing in the transcript...

funny, does someone know why it doesn't work ?

Cheers

At least in my small example.
Evaluate the code in the ClassProxy comment.
