[tex-live] Strange bug with l3kernel

I recently updated MacTex 2018 with Tex Live Utility and stumbled upon a strange bug. The following minimal example compiled with lualatex fails :

% !TEX TS-program = luaLaTeX
\documentclass{article}
\usepackage[utf8]{luainputenc}
\usepackage{fouriernc}
\usepackage{mdframed}

\begin{document}

\end{document}

Here are the relevant lines in the log :

> (/usr/local/texlive/2018/texmf-dist/tex/latex/l3kernel/expl3-code.tex
> ! Illegal parameter number in definition of \c__tl_i_ogonek_tl.
> <to be read again> 
> \crcr 
> l.26054   \__tl_tmp:w \c__tl_i_ogonek_tl  { 012F }
>                                                 
> ? 
> ! Illegal parameter number in definition of \c__tl_I_ogonek_tl.
> <to be read again> 
> \crcr 
> l.26055   \__tl_tmp:w \c__tl_I_ogonek_tl  { 012E }
>                                                 
> ? 

Everything compiles fine when reverting to the previous versions of l3experimental, l3kernel et l3package (46875, 46875, 46712 instead of the current 47705, 47718, 47705) or when removing one of the three packages used in the example or compiling with pdflatex.

So… I can’t figure out what is going on :-(

Anyway, many thanks for the TexLive team for delivering this wonderful piece of software :-)
