Hi all, So we're currently working on a long-overdue release of Cython with all kinds of snazzy new features. However, our automated testing system seems to keep turning up sporadic segfaults when running the sage doctest suite. This is obviously bad, but we're having a hard time reproducing this -- they seem to be *very* occasional failures while starting up sage, and thus far the only consistent appearance has been *within* our automated testing system (hudson). We've got a pile of dumped cores, which have mostly led us to the conclusions that (1) the problem occurs at a seemingly random point, so we should suspect some sort of memory corruption, and (2) sage does a *whole* lot of stuff when it starts up. ;)
So we'd love to see if other people see these same failures. Anyone want to try out the new cython? You can grab all the files you need here: http://sage.math.washington.edu/home/craigcitro/cython-0.13-beta/ There's a new spkg and 6 patches against the sage library. You can add the patches, sage -i the spkg, and then do a sage -ba, and voila! you should have a sage running the bleeding edge cython. (If that doesn't build, it means I forgot some patch somewhere -- there's a working sage-4.4.4 with the new cython in /scratch/craigcitro/cy-work/fcubed on sage.math if anyone wants to root around.) After that, run the full test suite as many times as you're willing, hopefully with and without parallel doctesting (i.e. sage -tp). Then let us know what you turn up -- lots of random failures, or does everything pass? Points for machines we can ssh into and generated core files (ulimit -c unlimited), and even more points for anyone seeing consistent/repeatable failures. I'd also be very interested of reports that you've run the test suite N times with no failures. -cc -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
