[xml/sgml-pkgs] Bug#293592: libxslt1.1: Setting xml:lang on / makes xsltproc segfault

[Vincent Lefevre]

Package: libxslt1.1
Version: 1.1.8-5
Severity: normal

This XSL stylesheet is buggy, but in any case, xsltproc shouldn't
segfault.

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
  <xsl:attribute name="xml:lang">
    <xsl:value-of select="'en'"/>
  </xsl:attribute>
</xsl:template>
</xsl:stylesheet>

dixsept:~> xsltproc test.xsl test.xsl
zsh: segmentation fault (core dumped)  xsltproc test.xsl test.xsl
