The failure occurs at compile time, but only under Saxon-HE (no failure under EE).

The submitter has simplified the test case to the following:

<xsl:stylesheet version="2.0" 
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

	<xsl:template match="root/*[last()]"/> 
	
</xsl:stylesheet>

and this version also fails in Saxon-EE.

Aside: I thought there was supposed to be an optimization that replaced this by match="root/[not(following-sibling::)]".

Indeed, the failure occurs while Saxon is performing this very optimization.

  • Status changed from In Progress to Resolved
  • Fix Committed on Branch 9.7 added

I have applied a patch to the constructors for PatternWithPredicate and AncestorQualifiedPattern to make sure that parent pointers and static context pointers are correctly set during this optimization rewrite. This fixes the test case.
