Greetings,

I just posted the attached mail to the docbook-apps list. Daniel 
Veillard pointed out that libxml and libxslt are quite old and that this 
bug has been fixed since then.

Indeed, verifying this with the Windows binaries provided by Igor 
Zlatkovic at http://www.zlatkovic.com/projects/libxml/ proved that the 
segfault went away and my document gets smoothly transformed again.

E:\Temp\libxslt-1.0.26.win32\util>xsltproc -version
Using libxml 20503, libxslt 10026 and libexslt 717
xsltproc was compiled against libxml 20503, libxslt 10026 and libexslt 717
libxslt 10026 was compiled against libxml 20503
libexslt 717 was compiled against libxml 20503

May I ask the libxml and libxslt package maintainer to upgrade the 
packages to a newer version that fixes the crash. Are you still the 
maintainer, Robert?


Thanks for your help,
Patrick

Greetings,

I just upgraded my XSL stylesheets from 1.50.1 to 1.60.1 and now 
xsltproc complains about an undefined namespace and segfaults on one of 
my documents. The culprit seems to be a fileref, on which xsltproc chokes.

Is this a stylesheet issue or an xsltproc issue? Can anybody help?


Thanks,
Patrick
