name() within an inline function

Description
From xsl:list, today:
I tested using the following code in oXygen 14.1 with Saxon 9.4.0.4.
<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ahf="http://www.yahoo.co.jp/tmakita">
<xsl:template match="root">
<xsl:variable name="slectFunc" as="function(*)"
select="ahf:funcGetChildElementByName('d')"/>
<xsl:sequence select="$slectFunc(.)"/>
</xsl:copy>
</xsl:template>
<xsl:function name="ahf:funcGetChildElementByName" as="function(*)">
<xsl:param name="prmElemName" as="xs:string"/>
<xsl:sequence select="function($a as element()) as element()*
{$a/child::*[starts-with(name(),$prmElemName)]}"/>
</xsl:function>
</xsl:stylesheet>
However Saxon returns following error.
System ID: D:\My Documents\Proj\XSLT-TEST\20130113-func\test.xsl
Main validation file: D:\My Documents\Proj\XSLT-TEST\20130113-func\test.xsl
Engine name: Saxon-EE 9.4.0.4
Severity: error
Description: 0
Is there any workarounds?
Regards,
Toshihiko Makita
It's a NullPointerException in NameFn, and a workaround is to use name(.) instead of name(). It seems the context item isn't being supplied as an implicit argument. Works OK on the 9.5 branch.

- Tracker changed from Bug to Support
- Status changed from New to Duplicate
The stacktrace in 9.4.0.4 starts:
java.lang.ArrayIndexOutOfBoundsException: 0
at net.sf.saxon.functions.NameFn.evaluateItem(NameFn.java:33)
at net.sf.saxon.expr.Expression.iterate(Expression.java:429)
at net.sf.saxon.expr.FunctionCall.preEvaluate(FunctionCall.java:199)
at net.sf.saxon.expr.FunctionCall.typeCheck(FunctionCall.java:137)
The problem appears to have been fixed in Saxon 9.4.0.6, though I haven't identified the specific bug fix that cured the problem.
