[pph] Initialize fields in default ctor for _Hashtable_iterator

[Diego Novillo, 2011-04-16 20:30:27]

I am committing this patch for David Li on google/main.

The patch adds explicit initialization to the fields of
_Hashtable_iterator in its default constructor.  David, could you
describe why this change was needed?  Will you be submitting for
trunk?

Tested on x86_64.  Committed to google/main.


Diego.

Geez, working on too many different branches.  This is *not* a pph patch.
