I've played with LPegLJ and found, than applying `jit.off` to several
functions made them (or perhaps some other functions) broken.
Test is on fail_jit_off branch at
https://github.com/funny-falcon/LPegLJ/tree/fail_jit_off
With jit.off(getfirst) in lpcode.lua
$ luajit tpe2.lua
luajit: ./src/lpcode.lua:374: cannot convert 'nil' to 'unsigned int'
stack traceback:

Without jit.off(getfirst) all works fine.
With respect,
