Hmmm... I see what you're saying.  But I only recompiled the VM,
pretending that it has a minor-version of 6 when in fact it only includes
the changes up to 5.  That's surely sneaky, in general... though in this
case I have the source code of the newest VM and of the plugin, and a
quick look suggests no major code-breaking changes between 5 and 6.

And the test cases all run, so something must be happy.

Thanks again
