Hi Eliot,
Got home from my new job and started looking into this. It turns out that this morning I found that I had a button bar that was stepping and part of the step was a Smalltalk garbageCollect to force collection before checking for instances. It may be something I don't need to do anymore, however it helps expose this seg fault. Both stack dumps were in the garbageCollect. I removed the button bar, uploaded the image, and ran it. CPU% dropped from 33% to 2%. I let it run all day. At some point it exited, for an unknown reason, as it was gone when I returned tonight.
I have reinstated the button bar, to help this bug occur, and uploaded it to the server.
Now I just need to enable -leakcheck. From sqUnixMain.c it looks like it takes an argument. What is that argument?
Thanks, Rob

While the heap corruption might be a bug in Cog it might also be heap corruption from external code (e.g. objects passed through FFI calls to external code that overwrites those objects' bounds).
There's a leak checker in Cog (see the -leakcheck argument in platforms/unix/vm/sqUnixMain.c) that can help you localise this. Its best to distrust your code before you distrust the VM, simply because thinking it's the VM can blind-side you to potential bugs in your own code or other parts of the system. The goal here is a reproducible case. If you get a reproducible case that doesn't use any external code then the bug is in the VM.
