>          URL: http://issues.apache.org/jira/browse/XALANC-544
>      Project: XalanC
>         Type: Bug
>   Components: XalanC
>     Versions: 1.9
>  Environment: win2k on ix86
>     Reporter: Alain Le Guennec
>     Assignee: David Bertoni
>      Fix For: CurrentCVS
>  Attachments: patch.txt
>
> Consirer the following stylesheet (the actual input document does not matter):
> <?xml version="1.0"  encoding = "ISO-8859-1"?>
> <xsl:stylesheet version="1.0" 
> xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
> xmlns:exsl="http://exslt.org/common";>
>       <xsl:template match="/">
>               <xsl:call-template name="T1">
>                       <xsl:with-param name="arg1" select="."/>
>                       <xsl:with-param name="arg2" select="$foobar"/><!-- not 
> defined -->
>               </xsl:call-template>
>       </xsl:template>
>       <xsl:template name="T1">
>               <xsl:param name="arg1" select="."/>
>               <xsl:param name="arg2"/>
>       </xsl:template>
> </xsl:stylesheet>
> If you run Xalan with this stylesheet in Debug mode, you get the following 
> message:
> Assertion failed: m_referenceCount == 0, file 
> xalan-1-9-0\src\xalanc\PlatformSupport\XalanReferenceCountedObject.cpp, line 
> 43
> In Release mode, Xalan just crashes.
> Note that if you remove the first "xsl:with-param" element, then Xalan 
> correctly prints the expected error:
> XSLT Error: The variable 'foobar' is not defined.Source tree node: #document. 
> (file://stylesheet.xslt, line 5, column 50.)
> Apparently, this is a regression w.r.t. Xalan 1.8.
> Best regards,
> Alain Le Guennec
