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== at 0x17113D: ???
