ID: 27236 User updated by: bo at theaddedones dot com Reported By: bo at theaddedones dot com Status: Open Bug Type: XSLT related Operating System: solaris 8, OSX 10.3, Redhat PHP Version: 4.3.4 New Comment: 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> Previous Comments: ------------------------------------------------------------------------ [2004-02-12 19:55:30] bo at theaddedones dot com 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 on line 0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27236&edit=1
