Description Daniel Berrangé 2012-03-26 17:05:31 UTC 
Description of problem:

$ xmllint  --xpath '/../foo' -
<foo/>
Segmentation fault

I'd expect an error message of some kind instead of a crash

Version-Release number of selected component (if applicable):
libxml2-2.7.8-6.fc16.x86_64

How reproducible:
Always

Gahh, fixed upstream, the problem was limited to xmllint though :-)

http://git.gnome.org/browse/libxml2/commit/?id=bdc64d6d5f5f30982279af23cfa2d3ab08ba34c4


paphio:~/XML -> xmllint --xpath '/../foo' tst.xml
XPath set is empty
paphio:~/XML -> echo $?
10
paphio:~/XML -> 

One more reason to make that upstream release I have been promising for months !
