[xslt] BUG: non-existent file in document()

[Peter Pawlowski <pawlowski vivisimo com>]

Hello,

When referencing a file using document(), if the file does not exist, an 
error is generated, but then xsltproc segfaults (RedHat 7.2):

[pawlowski@dev tmp]$ more xslexample.xsl
<?xml version="1.0" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="1.0">
<xsl:template match="/">
  <xsl:apply-templates select="document('/tmp/thisfiledoesnotexist')"/>
</xsl:template>
</xsl:stylesheet>

[pawlowski@dev tmp]$ xsltproc xslexample.xsl empty.xml
warning: failed to load external entity "/tmp/thisfiledoesnotexist"
Segmentation fault (core dumped)

[pawlowski@dev tmp]$ xsltproc --version
Using libxml 20430, libxslt 10024 and libexslt 715
xsltproc was compiled against libxml 20430, libxslt 10024 and libexslt 715
libxslt 10024 was compiled against libxml 20430
libexslt 715 was compiled against libxml 20430


This seems to happen in the general case, i.e. in xsl:value-of and 
xsl:variable as well.

Thanks.
