There was a period where a new GC algorithm had some teething issues, but those were resolved.

Where did you get the newest VMs?

The one from your report seems old... "VM: 201708271955"

What platform are you on?��

How are your starting your Image?

Can you move your development to a fresh download of latest 6.1 Image & VM and report if that has any problems?

Hi all

I have a 6.0 image which crashes on garbage collect. If I run "Smalltalk garbageCollect" it crashes. The crash log is attached. But I don't really understand that crash log. I run it with a 6.0 VM, tried it also with newest 6.1 VM and 7.0 VM, but always the same error.

I read here in the list about crash problems with GC, memory leaks and similar, but I really don't see what I could do.

Any pointers in which direction I could investigate?

Thanks and cheers,
Andreas
