Bug description: Creation zipfiles with duplicate names in PHP results in
crash Apache
Description:
------------
When creating a new zip-file with the "ZipArchive::CREATE"-function, and
there already is a zipfile with the given filename Apache will crash
without any warning (just a Vista error popup saying it has already stopped
working).
Reproduce code:
---------------
<?php
$zip = new ZipArchive();
$zipfile = "myveryownzipfile.zip";
if($zip->open($zipfile, ZipArchive::CREATE) !== true) exit("Can't create
file ".$zipfile);
// Add stuff inside the zip-file
$zip->addFromString('tmp', 'bla'); // temporary file within zip
$zip->close();
// Same code as above so two identical files are (tried to be) created
if($zip->open($zipfile, ZipArchive::CREATE) !== true) exit("Can't create
file ".$zipfile);
// Add stuff inside the zip-file
$zip->addFromString('tmp', 'bla'); // temporary file within zip
$zip->close();
?>
Expected result:
----------------
When the second file is created, it should give out the exit-error: "Can't
create file myveryownzipfile.zip".
Or it should give a "fatal error!"-notice of PHP itself saying the
filename already exists or simply that the (second) file could not be
created (e.g. "duplicate filename").
Actual result:
--------------
When activating this script (only with the creation of a single zipfile)
through a form, and submitting it repeatingly (fast(!)), a (Vista) error
pops up saying "Apache.exe doesn't work any longer" and Apache has been
forced to shut down.

An error occured which made the program function incorrectly. The program
will now be closed and you'll get a notice when a solution is available."
I installed/run PHP through the XAMPP-package
(http://www.apachefriends.org/en/xampp.html).
