Thank you for this bug report. To properly diagnose the problem, we

sorry,
in the 'reporduce code' the proper xsl would be (just mistyped it)
<xsl:key name="state_key" match="data" use="state"/>
<xsl:for-each
select="//data[generate-id()=generate-id(key('state_key',state)[1])]"><xsl:value-of
select="state"/>,
</xsl:for-each>

Description:
------------
i have a slew of xml data that i need to select unique values from ...
the easiest method is via the xsl:key ...
when i ever i use xsl:key to make a key (regardless of if i use or not)
the xslt processor (libxml2 '20507', libxslt 1.0.30 -> 1.0.36 (the
versions i have tried)) i get an 'xmlFree' error IF i compiled the
libxml with the debug-mem option...if not i crashes the Apache (1.3.29)
child via a bus error...
the error....
Warning: Unknown(): Memory tag error occurs :0x6637671 bye in Unknown
on line 0
Warning: Unknown(): xmlMemFree(6637691) error in Unknown on line 0
Warning: Unknown(): xmlMallocBreakpoint reached on block 0 in Unknown
on line 0
interestingly, the entire XSL process works fine, and returns a
properly converted document (even the keys work properly), it jsut dies
with the memory error..i'm guessing something funny with garbage
colleciton
Reproduce code:
---------------
the below should dump all the unique states in my data as a comma
separated list
<xsl:key name="state_key" match="images" use="state"/>
<xsl:for-each
select="//data[generate-id()=generate-id(key('state_key',state)[1])]"><xsl:value-of
select="state"/>,
</xsl:for-each>
save as a normal xslt file
try to compile using dom ala
domxml_xslt_stylesheet_file({your file})...
create some XML, and process the beast via 'process' you shall see the
error
Expected result:
----------------
no silly memmory failures
Actual result:
--------------
Warning: Unknown(): Memory tag error occurs :0x6637671 bye in Unknown
on line 0
Warning: Unknown(): xmlMemFree(6637691) error in Unknown on line 0
Warning: Unknown(): xmlMallocBreakpoint reached on block 0 in Unknown
