Description:
------------
This small OO script gives some memory leaks.


Reproduce code:
---------------
class ReleaseInfo
{
    const NAME_LONG                 = "PHPORB";
    const NAME_SHORT                = "orb";
    const VERSION_MAJOR             = 0;
    const VERSION_MINOR             = 1;
    const VERSION_MINOR_CHANGE      = 0;
    const VERSION                   = "" . VERSION_MAJOR . "." . VERSION_MINOR . "." . VERSION_MINOR_CHANGE;

    const SPEC_VERSION_MAJOR        = 2;
    const SPEC_VERSION_MINOR        = 4;
    const SPEC_VERSION_MINOR_CHANGE = 2;
    const SPEC_VERSION              = "" . SPEC_VERSION_MAJOR . "." . SPEC_VERSION_MINOR . "." . SPEC_VERSION_MINOR_CHANGE;

    const RELEASE                   = NAME_LONG . " Version " . VERSION;
    const RELEASE_TAG               = NAME_LONG . "_" . VERSION_MAJOR . "_" . VERSION_MINOR . "_" . VERSION_MINOR_CHANGE;

    public static function main($args)
    {
        echo NAME_LONG . ":";
        echo "\t" . NAME_LONG . " " . VERSION;
        echo "\t" . RELEASE_TAG;
        echo "\tCORBA/IIOP " . SPEC_VERSION . " (http://www.omg.org/cgi-bin/doc?formal/01-02-01)";
    }
}


Expected result:
----------------
Nothing to the standard output and no memory leaks.

Actual result:
--------------

I must have had --enable-debug missing in my last build, now I got the same leaks.
 [2003-08-03 15:05 UTC] cunha17 at uol dot com dot br 
With the latest CVS there is no memory leaks anymore, but I got core dumped at the end of script execution.
 [2003-08-04 05:39 UTC] stas@php.net 
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.
