Andreas found and fixed a problem in the VM, described here:


The bug affects loading of older image segments (from pre-closure images)
into newer images (with closure support).

The fix is not yet in any of the distributed VMs (except possibly windows?),
but if you do not mind building a VM from VMMaker and sources, it may
resolve your problem.
