Bug description: "Segmentation fault" - trying to inherit >2 classes and to call
parent constr.
Description:
------------
Description:
Segmentation fault occurs when trying to inherit more then two classes and
to call parent constructors (see example to understand how I'm trying to
do it).
When I comment last "call_constr()" call, the problem disappears.
Configure Command:
'../configure' '--prefix=/usr' '--with-apxs=/usr/bin/apxs'

Reproduce code:
---------------
class object {
function call_constr() {
$par=get_parent_class($this);
$this->$par();
}
}
class Graph extends object {
function Graph() {
}
}
class TwinGraph extends Graph {
function TwinGraph() {
$this->call_constr(); // calling parent constructor
}
}
class TwinBarChart extends TwinGraph {
function TwinBarChart() {
$this->call_constr(); // calling parent constructor
echo "Test";
}
}
$graph=new TwinBarChart();
Expected result:
----------------
Test
Actual result:
--------------
Segmentation fault
