This code:

$arr=array();
$arr=array_pad($arr, 65535, md5(microtime()));

causes this output:

[Fri Dec 28 10:01:38 2001]  Script:  './test.php'
---------------------------------------
zend_execute.h(62) : Block 0x081BD070 status:
Beginning:      Cached (allocated on ./zend_execute.c:1502, 12 bytes)
      End:      OK
---------------------------------------

backing that down to 65534 will cause no error.  Looks like that parameter is set to only allow 32 bit integers.

Try snapshot. http://snaps.php.net/
I don't see the error. If you have problem, please reopen.

Sorry, that should have been anything larger than 65535 will cause this.  Try like 80000.
 [2002-02-27 01:06 UTC] yohgaki@php.net 
With "80000" or "65536", I get the output.

Script:  '-'

Please try the latest snapshot from http://snaps.php.net/php4-latest.tar.gz , I'm pretty sure this has been fixed already, I can't reproduce it myself.

Could not verify this with 4.3.0-dev on Compaq Tru64 / Alpha
 [2002-08-19 15:02 UTC] nohn@php.net 
Verfied this on Linux/x86.

May be similar to http://bugs.php.net/bug.php?id=18743 and some array someone (Dan) closed today regarded to some int-value in Zend engine (don't remember anything more on this)

Just for the record, I haven't closed any array bugs today, nor yesterday if I remember correctly :)

FYI: cannot reproduce with a fresh CVS version on Linux (RedHat 6.2).

Fixed in CVS then.
