Hi,
I'm not sure what the issue is, but since you are on PPC, possibly something has gone wrong with the mechanism for saving generated machine code in the snapshot (which was built on x86)
Try:
self -F -s /library/self/0/Demo-4.4.snap
which attempts to load while abandoning any included machine code.
Otherwise, I suggest cloning the github tree, going to the objects directory and building a new snapshot from source:
self -f worldBuilder.self
(then "desktop open" to start the GUI)
Cheers, Russell

Or it could be a bit- or byte- ordering bug, IIRC.

Suggest you build a new snapshot from scratch, by typing in
'all2.self' _RunScript
Assuming you have the .self files.

Self process 19263 on GLTMac-2.local has crashed. Do you want to:
- Quit Self (optionally attempting to write a snapshot)
- Try to print the Self stack
- Try to return to the Self prompt
- Force a core dump
- Print the interrupted context registers
Your choice: 1 Enter snapshot name (hit return to omit snapshot) > No snapshot specified, will skip this step $

Russell informs me that all2.self has been replaced by worldBuilder.self. You could try that.
