[Fixed] Re: Access violation

A new alpha set of VM and images is available which fixes the lack of  
checking in VM slot manipulation primitives, and the REPL now  
refreshes its parser on every new loop cycle, eliminating these bugs.

However, parsing errors still can result in "an error occurred within  
the debugger" due to their still being input to read when the  
debugger tries to ask for input. (That input will of course just be  
the rest of the expression, so often invalid.) This doesn't have a  
real operational effect, but is annoying to have to look at. I'll try  
to fix this shortly.
