I think it crashes for a different reason: there are some unchecked
allocations in realloc(). This has nothing to do with overcommit.

Are you sure? With vm.overcommit_memory set to "2", the error should
happen during allocation.

Are you sure you need an account on the trac to report it? The http version
at least seems to accept essentially anonymous input.
Alternatively, I guess JP's suggestion should work fine. It might be even
better if some discussion is needed about what interface NTL should provide.

Yes, I tested that too. Just add print-function before and after the line

I probably assumed too much. But it felt wrong to say
“there is a problem building ntl but ntl upstream is happy
to talk to you about your needs” (and doing that anonymously
feels like a prank call).
I prefer the mailing list option and I am actually subscribed.
Still have to get to it.

Dear all,
This is an announcement for an engineer position at Bordeaux (France).
It is a position for 1 to 3 years inside the OpenDreamKit project. See

It is indeed a problem! The interfaces should be compatible. Adding a
_vector_ method to the GF(p) elements should be enough.

Doing "git-trac --log=DEBUG" probably works.
Of course the ideal solution would be for main to catch errors and present
Hi,
I think this is a bug:
sage: F.=GF(9)
sage: V=F.vector_space()

sage: W(b)

The cause is
sage: a._vector_()

Hi, we're trying to package Sage 7.4 for Debian and are running into a

Here is another solution, but it involves upstream fpylll. I'm not sure
how realistic it is, because of the auto-generated config.pxi:
(3) Ship the Cython-generated files with fpylll. This moves the
dependency on Sage from build-time to packaging-time.

Dear Joshua,
Welcome to Sage development! It is good idea to ask for a trac account
for the following reasons
* create a ticket on trac.sagemath.org that makes your project public
* upload your code changes on the git server and make your code
publicly available for discussion
Did you already
