[luatex] Core dump error

I'm having some problems using `\localleftbox` and `\localrightbox` in 
LuaTeX 1.10 (the TeX Live 2019 Pretest) and GregorioTeX.  In trying to 
diagnose this problem, I stripped things down to this simple test document:


%\localrightbox{Goodbye} % This one will trigger the error too.


This document complies just fine with 1.07 (which shipped with TeX Live 
2018).  With 1.10, however, I get a core dump:

This is LuaTeX, Version 1.10.0 (TeX Live 2019)
  restricted system commands enabled.

hnj_hyphenation: Assertion `tail != 0' failed.
Aborted (core dumped)

Did something change in `\localleftbox` and `\localrightbox` which I 
should be aware of?
