I suggest you use lua_pushliteral for string literals; it's good documentation.
lua_pushliteral is currently defined as lua_pushstring but in Lua 5.2
and previous versions it was defined as
#define lua_pushliteral(L, s) lua_pushlstring(L, "" s,
(sizeof(s)/sizeof(char))-1)
See https://www.lua.org/source/5.2/lua.h.html#lua_pushliteral
You may want to redefine lua_pushliteral back to this if you are
worried about strlen on literals.
It would be better for everyone in the Lua 5.4 git?
