Reported By: oka at ping dot uio dot no
Status: Open
Bug Type: Reproducible crash
Operating System: Linux
PHP Version: 5.2.6
New Comment:
function print_xml($node, $data) {
$this->print_xml($node, $data);
}
is an infinite recursion. You most likely want parent::print_xml($node,
$data);

Description:
------------
Code with a class and a subclass with constructor functions and a
separate function in both classes causes both the Apache 2.0.63 PHP
module and the cli that ships with PHP 5.2.6 to emit the SIGSEGV
signal.
Reproduce code:
---------------
<?
class Article {
var $ai;
function Article() {
}
function print_xml($node, $data) {
return "<" . $node . ">" . $data . "</" . $node .
">";
}
}
class Contribution extends Article {
function Contribution() {
$this->Article();
}
function print_xml($node, $data) {
$this->print_xml($node, $data);
}
}
$contrib = new Contribution();
print $contrib->print_xml("tagname", "New");
?>
Expected result:
----------------
<tagname>New</tagname>
Actual result:
--------------
I put a partial backtrace from gdb 6.4.90-debian online at
http://www.ping.uio.no/~oka/php-5.2.6-oka-SIGSEGV/php-5.2.6-oka-SIGSEGV.gdb-session.log
