Something strange is going on for sure. I have tried running the
"$VM CogVMMaker.image BuildSqueak45Image.st" step a few times with both
a Cog VM and an interpreter VM, and in all cases the image and VM are just
exiting somewhere in the middle of the process. No error messages, no core
dumps, just an exit. I am not seeing any consistent pattern as to when it is
exiting although I think it is happening during Monticello processing. I am
on a 64 bit linux box (BTW the "md5" command used in the shell scripts is
not present on my machine).
