[luatex] luamplib problem (?)

[Herbert Schulz]

Howdy,

I'm using a fully updated TeX Live 2014 on Mac OS X 10.10.1. I just tried to compile

\documentclass{article}
\usepackage{luamplib}
\begin{document}
A%
\begin{mplibcode}
beginfig(1);
fill fullcircle scaled 20; 
endfig;
\end{mplibcode}
B\par
\end{document}

with lualatex and got an error. It used to compile fine. The console error message is

...
/LuaMpost.tex:11: LuaTeX error ...texlive/2014/texmf-dist/tex/luatex/luamplib/l
uamplib.lua:393: attempt to concatenate field 'numbersystem' (a nil value)

l.11 \end{mplibcode}
                  
Note: I've got lua 5.2.3 installed but I thought it should be using texlua which is at beta-0.79.1 (TeX Live 2014) (rev 4971).

Please reply directly to me since I don't subscribe to this list.

Good Luck,
