The documentation on http://www.sagemath.org/doc/index.html is for Sage
v6.6.beta0. Shouldn't it be for Sage v6.5?

Hello,
a long standing issue is
sage: bool(piInfinity)
False
sage: bool(SR(3)Infinity)
False
http://trac.sagemath.org/ticket/12967
at which I'm having a naive stab (because it interferes with #14801).
Maybe I can learn something?
In the ticket the problem has been said having to do with Pynac,
Hi,
Just to tell that no later than two days ago, I had a bug in my code that
was caused by
bool(SR(0) Infinity) returning False.
I was about to post a message to sage-devel, but thanks to your post, I
realize this is a known issue.
Best wishes,
Eric.

Hello sage-devel,
I sent the following email to sage-release, but I think it really belongs
here. I'm looking for ideas on how to debug (or better, how to fix) the
problems with GP/PARI interface that are causing sage to hang.
Thanks,

Can you try
CXXFLAGS=-Wno-error=unused-parameter make
or maybe just CFLAGS. If it works we can add it as a workaround.

Yes, your suggested 'fix' works.
My standard CFLAGS and CXXFLAGS that was failing on zeromq:
CFLAGS=-march=native -O2 -fomit-frame-pointer -pipe -W -Wall
CXXFLAGS=-march=native -O2 -fomit-frame-pointer -pipe -W -Wall
The following work:
