[luatex] Crash with hyphenation patterns

Hello all,

With the minimal format file

\catcode `\{ = 1 \relax
\catcode `\} = 2 \relax
\catcode 32  = 9  \relax
\endlinechar = 32 \relax
\input hyphen.tex

everything works fine with either pdfTeX or XeTeX (TeX Live 2010 Pretest 
builds). However, with LuaTeX I get a crash:

This is LuaTeX, Version beta-0.60.1-2010052109 (TeX Live 2010/pretest) 
(rev 3685)  (INITEX)
  restricted \write18 enabled.
(/usr/local/texlive/2010/texmf/tex/generic/hyphen/hyphen.texAbort trap

Any idea why this is happening? (You can probably guess from the 
catcodes that this is LaTeX3-related.)
