I’ve committed the suggested changes to the repository, thanks for that.
I’ll be able to investigate the runtime crash in a couple of hours. My apologies for these unexpected issues; I hadn’t actually tried to run this thing on Windows yet (I’ve been doing most of my development on OSX and Linux).
Edit: the pzip crash appears to be intermittent. I saw it happen once, but now I can’t get it to happen again. Still investigating. . .
