Hi
I found an other issue that makes Gexslt crash. Here is
the more simple example I written that reproduces the
problem (not really minimal, but I can't reduce it more):
> cat gexslt-crash.xml
<test:report
xmlns:test="http://www.fgeorges.org/xslt/unit-test"
tested="hello-world.xsl"
tested-absolute=".../hello-world.xsl"
date="2006-09-21T11:30:55.142+02:00">
<test:tests id="false">
<test:title>False negative</test:title>
<test:test id="false.1" successful="false">
<test:expect>
<elem2 id="id"/>
</test:expect>
<test:result>
<elem1/>
<elem2 id="id"/>
</test:result>
</test:test>
</test:tests>
</test:report>
> cat gexslt-crash.xsl
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

exclude-result-prefixes="test xs"
xmlns="http://www.w3.org/1999/xhtml">
<xsl:template match="test:report">
<html>
<xsl:apply-templates select="
test:tests/test:test[not(xs:boolean(@successful))]"/>
</html>
</xsl:template>
<xsl:template match="test:test">
<xsl:apply-templates select="test:expect">
<xsl:with-param name="comparison" select="test:result"/>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="test:expect">
<xsl:param name="comparison" as="element()?" select="()"/>
<xsl:variable name="compare" as="node()*" select="
$comparison/(node() except
text()[not(normalize-space())])"/>
<xsl:for-each select="node() except
text()[not(normalize-space())]">
<xsl:variable name="pos" as="xs:integer"
select="position()"/>
<xsl:apply-templates select="." mode="mode">
<xsl:with-param name="comparison" select="$compare[$pos]"/>
</xsl:apply-templates>
</xsl:for-each>
</xsl:template>
<xsl:template match="*" mode="mode">
<xsl:param name="comparison" as="node()?"/>
</xsl:template>
</xsl:stylesheet>

gexslt: system execution failed.
Following is the set of recorded exceptions:
-------------------------------------------------------------------------------
Class / Object Routine Nature of exception
Effect
-------------------------------------------------------------------------------
GEXSLT root's creation Segmentation violation:
<000000000169003C> Operating system signal.
Exit
-------------------------------------------------------------------------------
GEXSLT root's creation
<000000000169003C> Routine failure.
Exit
-------------------------------------------------------------------------------
Interestingly, if you replace "$compare[$pos]" by the
equivalent "$compare[current()/position()]", the
transformation doesn't crash anymore.
Here is a full stack trace:
