Comment(by SimonKing):
Volker, I am ''not'' getting the segfault you reported.
With the current two patches, I obtain:
{{{
sage: R = PariRing()
sage: loads(R.dumps()) == R
True
sage: loads(R.dumps()) is R # I want to fix that!
False
sage: f = R('x^3 + 1/2')
sage: f.dumps()
'x\x9ck`J.NLO\xd5+\xca\xccK/\xd6+H,\xca\x8c\x071\xb9\x02\x80,\xaeBF\xcd\xc6B&\xbf\xdaB\xe6P\x8ex\x90H||E!\x0bDCNf\x12D\xbd^zj^|A%W\x01X\x07k(gE\x9c\xb1\x82\xb6\x82\xa1\xbeQkP![q[\x92\x1e\x00\xbc9
\xf7'
}}}
So, the question is whether we should fix it here, or open a new ticket
and make it a dependency.
