I see sigsegv in lxml tests:
1222/1364 ( 89.6%): test_xmlschema_import_file
(lxml.tests.test_xmlschema.ETreeXMLSchemaTestCase) ... Segmentation
fault
https://sage.math.washington.edu:8091/hudson/job/cython-devel-lxml-trunk-py27/890/console
Is that control flow related issue?
No, don't bother with that one.
It's been crashing at that point for ages and I can't figure out why. It
only crashes on sage.math, and only when running two of the tests in
combination (a threading test and the one above). So far, I couldn't
reproduce this on any other machine, nor is it any clear what may trigger
this. I'm pretty sure it's not a Cython related bug, though.
Ok, according to last 4 builds it's fails 75% so maybe try to run it
under gdb with bt hook?
I *know* where it fails. But that doesn't really tell me *why* it fails. As
I said, it only crashes when one of the threading tests runs before it. I
can only guess that the thread interaction somehow leaves libxml2 in an
inconsistent state, which then triggers a crash later on in the schema test.
