[pypy-dev] Looking for clues to consistent Seg Fault in PyPy 2.6.1

[Jeff Doran]

Hi,

Just an update on this problem.  I retested using the latest lxml source
from here <https://github.com/lxml/lxml> ( 3.5.0b2?) and a version of
PyPy-4.0 from here
<https://bitbucket.org/pypy/pypy/downloads/pypy-4.0.0-src.tar.bz2> that I
built for Debian 7.9.    The good news is I got much farther in the lxml
test suite then before, but the bad news is I still encountered my old
friend  SIGSEGV.  This is consistently occuring during
 test_delslice_negative2 in lxml.tests.test_elementtree.ETreeTestCase which
as I said is much further thru the suite of tests then previously.    This
is encouraging.

For now I'm still unable to use this combination so if anyone has a
 suggestion on how I might proceed to utilize both PyPy and lxml I would be
most appreciative.

Thanks.
- Jeff
