[Dev-luatex] lpeg/setmaxstack unknown

Hi, this fails: \directlua{ lpeg.setmaxstack(12345) } \bye ~/TeX/luatex/test$ luatex test This is LuaTeX, Version beta-0.70.2-2012062819 (TeX Live 2012) restricted \write18 enabled. (./test.tex ! LuaTeX error <\directlua >:1: attempt to call field 'setmaxstack' (a nil valu e) stack traceback: <\directlua >:1: in main chunk. l.3 } WTF??? :)) (seriously: it's in the lpeg documentation - but I guess the 0.70.2 has an old version of lpeg? Perhaps without setmaxstack)? Patrick
