Re: [xml] libxml2-2.6.26: xmlXPathCacheNewString(): Bus error (coredumped)

[Guang Yang <yg_cn yahoo com>]

Additional info: it seems if quotes (single or double) appear between brackets [] in an attribute of a tag, segmentation fault or bus error will happen.
 
 e.g.  <xsl:template match='h:meta/@http-equiv[.!="refresh"]'/>
 or   <xsl:template match="*[ class='myclass']"></xsl:template>

Thanks Kasimier, here is the simple stylesheet:

<xsl:transform xsl:version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
      xmlns:h ='http://www.w3.org/1999/xhtml' exclude-result-prefixes='h'>
<xsl:template match='h:meta/@http-equiv[.!="refresh"]'/>
</xsl:transform>

It seems the <xsl:template> line is causing the trouble, somewhere near the double quotes.
