Bug Type: XML related
Operating System: Linux glibc 2.3.4
PHP Version: 4CVS-2005-07-30
New Comment:
Still seeing this same issue in PHP 4.4.7 (two years later?!) with the
CPanel build of Apache and PHP on Centos "4.5". Seeing core dumps with
vBulletin's cron job, upgrading to PHP 5.x not a short-term option on
the shared box in question.
--------------------------------------------------------
Back trace from the vBulletin cron.php throws me:
#0 0xffffe410 in __kernel_vsyscall ()
#1 0x4a2137a5 in raise () from /lib/tls/libc.so.6
#2 0x4a215209 in abort () from /lib/tls/libc.so.6

etc etc etc
--------------------------------------------------------
Instant "*** glibc detected *** double free or corruption" occurs:
class test {
function test() {
// initialize parser
$this->parser = xml_parser_create();
xml_set_element_handler( $this->parser,
array( & $this, "startTag" ),
array( & $this, "endTag" )
);
}
}
$parser = new test();
--------------------------------------------------------
Sigh, I'm guessing we may be SoL on this one...

Try freeing the parser via xml_parser_free()
