Hello,

I'm sorry, I didn't see this issue until right now.

As you have correctly noted, lbForth does have bugs and quirks. However, it's mainly a vehicle for personal experiments and may not be suitable for public consumption. Caveat emptor. I'm not actively developing it now, though that may change some time in the future.
