I'm using LUA 5.1
I checked 5.3.4, lstate.c has not significant changes in these places,
setnilvalue in lobject.h has.
#define settt_(o,t) ((o)->tt_=(t))
#define setnilvalue(obj) settt_(obj, LUA_TNIL)
It seems it should not crash with this implementation.
I will try. Thanks.

What version of Lua are you talking about? Lua does not use reference count
and nowhere in its code you would find a 'refCount' field.
