see http://mail.gnome.org/archives/xml/2003-October/msg00320.html

I can duplicate the segfault with 2.6.0, but not with 2.5.11. I'll attach
the offending file that Petr provided to the mailing list.

Comment 2 Daniel Veillard 2003-10-28 15:45:31 UTC

Okay, it was a nasty case in the new error handling
code, which was not cautious enough about the scope and
content of some informations passed. This is now fixed 
in CVS,

  thanks !

Daniel

Comment 3 Daniel Veillard 2003-11-06 00:02:41 UTC

Should be fixed in libxml2-2.6.2,
                                                                     
          
  thanks,
