Sounds great!  Do you think those changes will be available for the release?

I also found another, simpler, way of causing the error.  Using a new 
build (skipping over the errors from the libraries), just press C-c in 
the repl.  Then enter 0 to select the continue restart.  You get a segv 
at address 0.

Based on your patch and your comments, I think your full patch will be 
needed to fix this.
