Hello!
I started rewriting my personal macros for luaTeX and so far it was
a delightful experience.
However, one of my papers fails to compile with a fatal error
"interwoven alignment preambles are not allowed", while it compiles
perfectly in plain pdfTeX.
A minimalistic test case is this:
\def\\{\hskip 1.5pt plus 1fil\hbox to 0pt{\hss\vrule\strut\hss}\hskip -1.5pt plus -1fil}
\halign{\hfil#~~&&\hbox to 2em{\hfil#\hfil}\hskip3pt\cr
$S[i]$ &1&3&9\\&2&3\\&4\\&3\\&0&3&7\\&6\\&6\cr
}
I am compiling this with luaTeX beta-0.79.1 from TeX Live 2015
in Debian Jessie (using the plain luaTeX format).
Do you have any hint on what I am doing wrong?
Have a nice fortnight
