Lua 5.3.4 and LPeg 1.0.1 dumped core on me

[Sean Conner <sean@...>]

  So I'm participating in this years National Novel Generation Month [1] and
I finished my entry.  While generating the output, I had to use Lua 5.1
because Lua 5.3 would crash---hard.  

[spc]lucy:~/writings/nanogenmo/2018>lua run.lua TheEmeraldCityOfOz.txt >/tmp/output
Segmentation fault (core dumped)
[spc]lucy:~/writings/nanogenmo/2018>lua-51 run.lua TheEmeraldCityOfOz.txt >/tmp/output
[spc]lucy:~/writings/nanogenmo/2018>

  I'm not sure what's going on.  From the core dump:

System specifics:  x86 Linux (so 32-bit).  I haven't tried it on any other
system yet.  But the code is available:

You may need to modify run.lua to comment out two lines of code:

to get it to run (or not, in my case).

And as I said, Lua 5.1 works with no issues.  Oh, I just noticed---my Lua
5.1 is pulling in LPeg 0.12, not LPeg 1.0.1.  Hmm ...
