Re: Crash in wrapper_base.cpp

Hmmm, I tried running your sample code and I seem to be getting the same
results each time.  What lines did you modify between tests?

I tried removing "  v[obj] = obj\n" and "  v[a[i]] = nil\n" for the run that
doesn't use keys as indices.

Seems like using an object as a key is perfectly ok.

>From http://www.lua.org/pil/17.2.html:

     *Once we use an object as a key in a table, we lock the object into
existence. Lua cannot collect an object that is being used as a key*

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
