I too am seeing crashes. Yesterday updating a Squeak image failed. I suspect display changes (because the e ruction engine code has been quite stable for many months) but without a reproducible case we cannot be sure. So I shall be trying to create a reproducible case for my crash. I shall:
- take copies of image and changes so that each time the test is run the changes and image files are at the same point - drive the test via the command line so that the ui does not introduce variability
Alas since my case involves network interaction I cannot control how long it takes to fetch remote package files nor the exact set of packages updated, but the update stream uses update maps which should hopefully provide some consistency between runs
Hi Eliot, For now I do not have a reproducible case for these issues. Now I got another interesting crash. Happened again while executing normal Pharo code. Just it's the first time I see in the stack trace `INVALID RECEIVER`: `0x7ffeef771fb0 M INVALID RECEIVER>do: 0x1071c60c8 0x1071c60c8 is a forwarded object to 0x34db1ad30 of slot size 1 hdr8 .....`

Hi Andrei,
if something reproducible shows up you can upload the image and changes to ftp.mirandabanda.org (cogftpuser c0gg1ng) with instructions on what you did and let me know. I'll take a look.

Is this fixed? Is there an easy way to reproduce this? It looks like a call-back bug to me, but based on the second stack trace, it looks like missing pinned objects.

Closing for now.
Closed #402.
