Re: recursively traverse globals table from C API

[Chris <coderight@...>]

The specific problem is with the parsetable(L, -1) recursion:

      if (lua_istable(L, -1)
      {
          parsetable(L, -1);
      }

When that goes into parsetable lua_next is going to use -1 as the
table index.  -1 would be the nil just pushed.  I believe using -2
would work though.
