mod() function broken on linux Alpha (was: Re: [xslt] libxslt build problems on linux-alpha?)

[Geert Kloosterman <geertk ai rug nl>]

Hi Daniel, all,

I've done some more research on the problem.  I did a

     xsltproc -v patterns.xsl db100.xml 2> patterns.log

and compared the logs from both machines:


    --- patterns.log.i386   Wed Jun 26 17:54:38 2002
    +++ patterns.log.alpha  Wed Jun 26 17:54:25 2002

The problem seems to be the "mod" statement.  For example, the
following stylesheet:

    <?xml version="1.0" encoding="utf-8"?>
    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                    version="1.0">

      <xsl:output method="text"/>

      <xsl:template match="/">
        <xsl:for-each select="table/row[id mod 3 = 2]">
          <xsl:value-of select="id"/>
          <xsl:text>&#xA;</xsl:text>
        </xsl:for-each>
      </xsl:template>

    </xsl:stylesheet>

generates (using db100.xml again) on i386:

    0002
    0005
    0008
    ...
    (left a couple out to save space)
    ...
    0095
    0098

but on alpha the output is just:

    0002
    0005

The test documents were identical. 

On i386 the output of the following stylesheet is "OK", on alpha it's
"Ooops!". 

    <?xml version="1.0" encoding="utf-8"?>
    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                    version="1.0">

      <xsl:output method="text"/>

      <xsl:template match="/">
        <xsl:choose>
          <xsl:when test="8 mod 3 = 2">
            <xsl:text>OK&#xA;</xsl:text>
          </xsl:when>
          <xsl:otherwise>
            <xsl:text>Ooops!&#xA;</xsl:text>
          </xsl:otherwise>
        </xsl:choose>
      </xsl:template>

    </xsl:stylesheet>
