Subject: Re: DOCBOOK-APPS: xsltproc segfaults with 1.51.1


Hi,

The following is my version that segfaults:
-------------------------------------------------
Using libxml 20420, libxslt 10018 and libexslt 709
xsltproc was compiled against libxml 20421, libxslt 10018 and libexslt 709
libxslt 10018 was compiled against libxml 20421
libexslt 709 was compiled against libxml 20421
-------------------------------------------------

Indeed using 
ftp://ftp.gnome.org/pub/GNOME/stable/redhat/i386/libxslt/libxslt-1.0.18-1.i386.rpm
I don't get anymore segfault, just:
-------------------------------------------------
Error Undefined namespace prefix
xmlXPathCompiledEval: evaluation failed
-------------------------------------------------

And this version looks slightly older than Mandrake (above) one:
-------------------------------------------------
Using libxml 20420, libxslt 10018 and libexslt 709
xsltproc was compiled against libxml 20419, libxslt 10018 and libexslt 709
libxslt 10018 was compiled against libxml 20419
libexslt 709 was compiled against libxml 20419
-------------------------------------------------

So now, what's the problem(s):
- a bug in libxslt ?
- a bug in the 1.51.1 XSL?
- a bug in the compilation/packaging step?

Camille.
