Hey guys:
I was wondering... So, I have my local install of Sage 7.1 from source. I
didn't get the source using git, I downloaded it from the website. I've
made a local repository for Sage on my computer, and also made a remote
repository for it on my github. However, I don't think it is connec
Then making it Expression.laurent_polynomial() but allowing
polynomial with ring=LaurentPolyRing as argument seems to be
the best interface.

I would certainly yes! If

Sorry, forgot to mention: all this is happening under Sage 7.0. Under 7.1
it is much worse, I get a silent "Memory exhausted" crash the FIRST time
round, without a report. So it seems something really broke between 7.0 and
7.1.

When I invoke a function like
BIG=myfunction(somevars)
where BIG gets to ~50% of RAM in a concrete case, re-running that function
again results in a memory error. If I release BIG first, say put BIG=0,
then it works. However, looking at top, I can see that only about half of
the memory alloca

This behavior would not fit well with

It will be great to have axes labels on 3d plots !
Good luck for your ticket !
