And note that
sage: DyckWords(4r, 2r).cardinality()
9
sage: type(_)
<type 'int'>
Which might explain part of the behavior.

PS: the change certainly comes from #17852 which makes now binomial(3,2)
return a Python int if the first argument is a Python int.

the failure is still very much here. I think it can be triggered somewhat
reliably with
./sage -bt src/sage/combinat/dyck_word.py
while at the same time
./sage -t src/sage/combinat/dyck_word.py
passes without error. This is really strange.

Vincent, did you also upgrade to 6.7.beta0 or 6.7.beta1 from a previous

I just finished building 6.7.beta1 after "make distclean", and this time
I
can't reproduce the error.
Unfortunately, this doesn't really explain what happened earlier, and
there
is still the possibilty that
the error is random.
I will continue to investigate this by running ptestlong a few more
times;
if I find something out of the
ordinary I'll report back here.

Strange. I'm also trying to find out what triggers the error, no

yet.
Jan Keitel also encountered this error (
http://trac.sagemath.org/ticket/18237#comment:6) -- and I'm sure
that there are others with the same problem.

Hello Benjamin,
Indeed, it was after a "make ptestlong" or something similar. And it
reproduced on both sage-6.7.beta0 and sage-6.7.beta1.
The error is very strange since it corresponds to a test of some
return
type. I will try to get something more verbose. And there is no
caching
involved as far as I can tell...

Hi Vincent,
well, at least I'm not the only one. For now, I don't really have a
clue
regarding where this could come from.
I'm still compiling a clean version of 6.7.beta1, but now I guess
that
won't change much.
The circumstance that this error only seems to appear after a series
of
doctests (I suppose you ran "make
ptestlong" too?) confuses me. Could this point towards something like
caching or memory leak?
