Thanks, Dan.
I'll give that a try. I had figured that was probably the case - but
had no way to efficiently figure out what had gotten chomped on by the
crash, as I'm very far from a Python guru.

Hi again,
in the meantime I made some progress on my problem:
I use FreeMonoid to generate the set of finite words, I use FormalSums
over the integers to get the linear combinations and I wrote a simple
method to multiply two such formal sums (should this go into the class
of FormalSums?).

Is this what you're looking for?

It is good to keep the ginac ordering internally. The user friendly
ordering is more expensive so it slows down com

My first guess for #9046 is that the problem is located within the
last line of collect : return x + (*this-x).expand();
In that case (*this-x).expand() should be zero but looks like:
-x^2 - 2*y^3 - y^2*z + x^2 + 2*y^3 + y^2*z
I think that whithin the call to expand(),

Hi,
Maybe it is a good thing to keep the same order as ginac internally
and your more usual ordering for printing.
However if you'd better not duplicate code, I can look at the "-
x^2+x^2" part of bug #9046.
Now I may understand a big enough part of pynac code to do that.
But if you'd better use t

It seems it has solved my issue, many thanks all of you; I'll attach a
snipped of code next time.
I knew Sage is based on Pyton, but what I don't know is where "the
first ends and the second begins", so I usually think my issue is a
Sage's one...
Anyway, thank you: it was helpful.

This is actually a Python question. It would of course be very
dangerous if variables defined outside a function would influence w
Hi everybody.
I'm experiencing problems with global variables in Sage. In
particular, I noticed that if I create a global variable, that one is
known everywhere and it's possible to call it everywhere. If I make an
assignment to a variable with the same name of the global one, but
inside a function
Ok, I have finally looked at the comparison functions and exchanging :
cmpval = seq[0].coeff.compare(other.exponent);
by
cmpval = -seq[0].coeff.compare(other.exponent);
in mul::compare_pow (mul.cpp:1265) seems to prevent the above bug from
happening.
It seems to fit better with the change made by W
