I have reduced it to this plain tex example
\catcode`\@=11
\input switch.def
\input babel.def
\input luaotfload.sty
\bbl@patterns@lua{serbian}
\righthyphenmin=3
\catcode`\@=12
%\font\test={OldStandard:mode=node;script=cyrl.SRB;language=DFLT;+tlig;}
%works
\font\test={OldStandard:mode=node;script=latn;language=DFLT;+tlig;}
%fail
\test
oo^^^^0302xx
\bye
The chars are all ascii, no cyrillic involved.
I have also reduced the pattern: One can remove almost everything
from (local copies ...) of hyph-sh-latn.tex and hyph-sh-cyrl.tex. It
breaks if this pattern remains:
\patterns{
2o1
}
