2.5.2 XSLTC compiler causes sporadic runtime data loss 

           Summary: 2.5.2 XSLTC compiler causes sporadic runtime data loss
           Product: XalanJ2
           Version: 2.5
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: org.apache.xalan.xsltc
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: chris5@directbox.com


Found a nasty bug:

When compiling the following example xsl with 2.5.2 or CVS (10 Dec) I recieve 
sporadic data loss when transforming the example xml.

Error with: win2k, xp; xalan 2.5.2, cvs; Xerces 2.4, 2.6; JDK142_02, 141_02, 
BEA Jrockit81sp1

Works fine with xalan251, and works also with Stylesheet compiled with 251 and 
transformed with 252, (so I guess it's the compiler)

The error occures with 252(binary) with a probability of 50%
                  with cvs (11. dec) 25%
The Pattern of good/wrong transformations stays the same for the example (even 
when rebooting) unless you change the code.


The example:
I tried to reduce it to the min.  I didn't saw the error when deleteng more 
lines. Changing the file changes the pattern of good/wrong. A bigger XSL causes 
a greater probability of the transformation failure.

following line in xsl causes the trouble:

<xsl:param name="buttons_size" select="(count(..//field/menu) * 
(&MENUTOOL_SPACE;+&FIELD_SPACE;)) + (count(..//field/button) * 
(&BUTTONTOOL_SPACE; + &FIELD_SPACE;)) + (count(..//field/value[@type = 'date']) 
* (&BUTTONTOOL_SPACE;+&FIELD_SPACE;))"/>

$buttons_size is sometimes 0 (should be 35)


I use a template for transforming.
