Re: HELP - leak in lua 5.0.3

Sory, I think I dind't explain well :(
You don't need to pass countreferences and findallpaths as a parameter of traverse. Inside these functions there's a definition of the function that should be passed to traverse and the call for traverse.
So, instead of traverse(countreferences(a)) you should use countreferences(a).

I'll see the problem with the version.

I forgot to post what I am doing:

Here is how I try to use it. Is it OK. ?

dofile('luatraverse.lua')
a=12
b={}
b["test_key"]=a
traverse( countreferences(a) )

Hi,

Here is the tool. You can implement a function that gives you the
information you want and then call the function traverse passing your
function as a parameter. As an example, you can look at the functions
'countreferences' and 'findallpaths'. But if these functions already gives
you all the information you want... well.. that's better =)
But it hasn't been fully tested yet. Please, report me if you find any bugs.

Thanks,
Alexandra.

        You can do that in Lua itself, using some reflexive facilities. I
guess
        someone in the list did some tool for this. A student of mine also
        wrote such tool (to traverse all live objects of a state). If she is

        not in the list, you may contact her directly:
