PHP version: 5.2.6
PHP Bug Type: Reproducible crash
Bug description: SIGSEGV crash after calling inherited function in subclass
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
