Yes, it crashes with a seg fault. Definitely a bug.

It crashes my image too, but I'm using an older linux vm.
Dave, is this fixed with the new and shiny 4.0.2-2172 vm?

No, we do not have a fix for this. On 4.0.2-2172 I do not get a seg fault, but the VM locks up 100% cpu. So we see various symptoms, but no fix has been proposed and it is still definitely a bug.

I do not see this issue as a concern for Squeak 4.1 release. It is a pre-existing VM condition, unrelated to the image version.

The CogVM doesn't have this issue, so it probably has a fix.

The underlying issue seems to be that we should get a DNU for this:

1 value: (CompiledMethod allInstances anyOne)

Cog correctly gives a DNU and the interpreter VM does not. It either evaluates to the argument (i.e. a CompiledMethod), or it crashes the VM.
