No crash here, but I still got "UNKNOWN:0" as var_dump's output.

Reproducible only with HEAD & 5.0.x.
<?php
class A {
function A($arrayobj) {
var_dump($arrayobj);
}
}
class B {
}
new A( new B() );
?>

Behaviour is reproducible using 5.00 on Fedora Linux (core 2).
There's an ongoing discussion of the behaviour on the Sitepoint forums
here:
http://www.sitepoint.com/forums/showthread.php?t=195284
By way of a summary, it appears that the problems occur when
constructing a number of new objects without assigning them anywhere,
so:
new A( array( new B(), new C())); // fails
$a = new A( array( new B(), new C())); // fine
some_function( array( new B(), new C())); //fine

Description:
------------
When I pass an array of objects without first initializing them with a
variable, I get either a crash or error (Depends on whether if its
array).
Reproduce code:
---------------
class A {
function A($arrayobj) {
while(list($key, $value) = each($arrayobj)) {
echo $value->spit();
}
}
}
class B {
function spit() {
return 'This is class B' . "\n";
}
}
class C {
function spit() {
return 'This is class C' . "\n";
}
}
new A( array( new B(), new C()));
Expected result:
----------------
I got this error:
This is class B
Fatal error: Call to a member function spit() on a non-object in
If I do:
$b = new B; $c = new C;
new A( array($b, $c));
It works but very long winded.
Another bug here causes Apache to crash:
class A
{
function A($value) {
echo $value->spit();
}
}
class B {
function spit() {
return 'This is class B' . "\n";
}
}
new A( new B());
