Unable to reproduce on OSX, or FreeBSD 4.6.  Check your local install agian please.

re-opening, seems I checked the wrong logfile on FreeBSD.  It does occur there as well.  

Unable to reproduce here.  Could you provide the shortest possible script that reproduces this?

Oh, my script was:

  $a = array(1,2,3);
  foreach($a as $s=>$s);

tested with current CVS.

Crashes here on OSX and FreeBSD with latest CVS.

Try using the $_SERVER variables as your array.

No segmentation fault, however a whole bunch of memory leaks.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

The crash is gone. The remaining memory leaks are the result of a recursive reference to the $s variable.
