Description:
------------
Returning large numbers of objects in an array seems to cause
segmentation faults or other memory related errors.
Our memory limit is set to 1024M; that should be the only non-standard
setting.
PHP Version => 4.4.4-pl2-gentoo
System => Linux nitrogen 2.6.13-gentoo-r3 #2 SMP Thu Oct 20 19:23:03

Reproduce code:
---------------
testFunc();
function testFunc(){
for( $i =0; $i < 100000; $i++ ){
$line = new ReportLine();
for( $j = 0; $j < 40; $j++ ){
$line->addData("this is a bug");
}
$lines[] = $line;
}
return $lines;
}
class ReportLine{
var $bool;// = true;
function ReportLine(){
// $this->bool = true;
}
function addData($value){
if( $this->bool ) $this->data[] = $value;
}
}
Expected result:
----------------
No output.
Actual result:
--------------
This results in a segfault. (Some values of the i limit gave me ***
glibc detected *** double free or corruption (fasttop):
0x0000000000XXXXXX ***) Lower values for the $i counter will result in
things running okay. Try setting it higher if the issue doesn't occur.
Removing the var declaration will fix the problem. Assigning a value to
it during the declaration will have no affect on the bug. Assigning a
value in the constructor - with or without a var declaration - will
cause things to work fine.
