[xslt] crash in libxslt 1.0.9


I get a crash when running the attached stylesheet.  It is getting pretty
deep into libxslt and I don't know exactly why it does, but I've made the
following observations:  

the namespace information (ctxt->nsNr,  ctxt->namespace[0]) that eventually
gets used in xmlStrEqual contains invalid pointers
it crashes near the end of the stylesheet (the xsl:apply-templates
select="exsl:node-set($sadoc)/node()")

I have tried to find a simple case that has the same problem to no avail.
Will post more if I know more, just wanted to see if the stack trace looks
familiar to a known/resolved issue.


C:\test>xsltproc --version
Using libxml 20412, libxslt 10009 and libexslt 702
xsltproc was compiled against libxml 20412, libxslt 10009 and libexslt 702
libxslt 10009 was compiled against libxml 20412
libexslt 702 was compiled against libxml 20412
