Hi,
-- long-post-warning --
I run into segfaults using a python2.3, gcc 2.95.2 - build (yes I know,
mighty old compiler :-):
Lib versions:
lxml 1.1.2
libxml2-2.6.23
libxslt-1.1.15
Tests work fine with everything gcc3.4.4-built, using python2.4 (same lib
versions), see below.
Both segfaults seem to arise when an error is raised internally (though it
is
unclear why the first is an error - it does not raise an exception when run
under python2.4/gcc3.4.4).
1. Using unprefixed namespace:
python2.3
Python 2.3.4 (#6, Jul 20 2004, 11:09:38)
[GCC 2.95.2 19991024 (release)] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> from lxml import etree
>>> elt = etree.fromstring("""<RvXML xmlns="myURI"></RvXML>""")
Segmentation Fault (core dumped)
