crunch creates zero byte files when used standalone

I extracted the tar on my raspberry pi (uname is Linux raspberrypi 4.9.35-v7+) and installed luarocks to install lfs.

I copied crunch.lua from ./bin to ./lib so that it could find parser.main.

I made a simple test script which consisted of a table declaration, a loop populating it with random values, and then a second loop printing it.

I then ran lua crunch.lua test.lua. The resulting test.cr.lua file had a size of zero.

However, crunch still works in game.

I just realized that, due to this folder structure, it's not including anything in crunch. I have altered the filesystem list to include the working directory (added a true to the lib.list in loadModules() in crunch.lua). I now get an error, instead:
test.lua:eof: ./parser/main.lua:1160: attempt to index local 'toke' (a nil value).

I suspect this is because I was using Lua 5.1. I switched to 5.2 (and blew away the LFS stuff, replacing it with a hardcoded list of libs because I was having a hard time with luarocks) and it works.

Interesting... Is it really "toke" or is it "token"?
I'm quite surprised because I don't see any way the function readToken is able to get a nil argument.
Would you mind giving me the output of the --debug option? That should include a traceback.
(I'm a bit short on time this evening to switch my OS and create a Lua 5.1 test.)
PS: Nice to see somebody using it outside OpenComputers. :)
