Saxon 6.4.4 (out of memory) vs. 6.2.2 (works fine)

Hi Michael Kay,

just downloaded 6.4.4 of my favorite xslt parser and tried to parse 
my documents but i got an Out Of Memory Error.

Dont know why, but maybe its a bug??
It works fine with version 6.2.2.

Parts of my stylesheet looks like this:
[...]
<xsl:template name="ansprechpartner">
  <xsl:variable name="setid" select="ancestor-or-self::set/@id"/>

  <xsl:variable name="kontakt">  
    <xsl:call-template name="findkontakt">
      <xsl:with-param name="chunk" select=".."/>
    </xsl:call-template>  
  </xsl:variable>

  <xsl:if test="$kontakt/*">
    <!-- test for children because temporary trees are always true -->
    [...]
  </xsl:if>
</xsl:template>

If i comment out the section with <xsl:if test="$kontakt/*"> no 
memory error occurs. 
But when i replace the xsl:if tag with
  <xsl:message>
    ##   <xsl:value-of select="$kontakt/kontakt/@id"/> ##
  </xsl:message>

i get an error again.

i would guess that i am not clever enough to make it right, but as it 
works fine with 6.2.2. it might be of interest for you. If so, i can 
send you the completet source code and error messages...
If not, just forget about it.
