Hi Panagiotis,

Thanks for trying the 1.9 series :)

Indeed, the debugger needs to be updated to understand the VM. The
problem is that now we have two kinds of stacks -- the interpreter
stacks and the VM stacks. I'm hoping to fix this situation within the
next couple weeks.

Until then, yes, some brokenness.

Cheers, and let us know how things are going for you.
