In ltable.c (Lua 5.0.2), beginning at line 492 (in
luaH_set): else if
(ttisnumber(key) && nvalue(key) != nvalue(key))
luaG_runerror(L, "table index is My compiler warns that this _expression_ is always false. It
sure looks that way to me. The updated code in 5.1.1 still looks to me like it
winds up doing the same thing (after several layers of macro expansion). If I
turn on optimization, I’m sure this code will be eliminated. So, can anybody weigh in on this? Is this a bug? If not, why
not? Thanks Tom -- |
