Hi,
with the latest LuaMetaTeX upload (running on Linux x64),
\normalunexpanded tries to write to address 0 and therefore
segfaults:
\normalunexpanded{abc}
\starttext
\stoptext
ConTeXt fails with
mtx-context | fatal error: return code: 139
The most interesting message from valgrind is
==53200== Invalid write of size 4

==53200== If you believe this happened as a result of a stack

==53200== main thread stack using the --main-stacksize= flag.
==53200== The main thread stack size used in this run was 8388608.
Best regards,
Marcel
