Description:
------------
While filling an array with about 400.000 Elements on a solaris box took several seconds to be done. On other OS or for example Java und Sun took only a few mill-seconds.

The debugger reports, that php ist trying to fetch memory for every element in the array. This is the reason why it get so slow.

I have tried different Solaris Versions and different php versions. It is the compination of solaris and php.
Linux und Solaris (same hardware) is much more faster.

Reproduce code:
---------------
<?php
               function GetMicrotime(){
               list($microseconds, $seconds) = explode(" ",microtime());
               return ((float)$microseconds + (float)$seconds);
               }

               $start  = GetMicrotime();
               $ende  = GetMicrotime();
               for($i=0;$i<50000;$i++)
                       {
                               $great_dump[] = array(1234,1234,1234);
                       }
               $ende  = GetMicrotime();
               $time  = $ende - $start;
               printf("%.10f",$time);
               echo "\n";
               echo sizeof($great_dump);
?>

Expected result:
----------------
less then one second

Actual result:
--------------
took me about 6,3 seconds
