Description:
------------
If a zip file contains more than 8xx files, ZipArchive::open returns ZIPARCHIVE::ER_READ. It's working under 32bit, but failling under 64bit systems (I tried two amd 64 systems).

5.2.1 and php5.2-200703201930 doesn't work.

Is this really a php issue?

Reproduce code:
---------------
#!/bin/sh
rm -rf test1 test2 test1.zip test2.zip
mkdir test1 test2
cd test1
php -r 'for ($i = 1; $i < 800; $i++) system("touch test$i.txt");'
cd ../
zip -r test1.zip test1 > /dev/null
php -r '$zip = new ZipArchive(); var_dump($zip->open("test1.zip")); var_dump($zip->numFiles);'

cd test2
php -r 'for ($i = 1; $i < 876; $i++) system("touch test$i.txt");'
cd ../
zip -r test2.zip test2 > /dev/null
php -r '$zip = new ZipArchive(); var_dump($zip->open("test2.zip")); var_dump($zip->numFiles);'


Expected result:
----------------
[mas@sw-nbk01 zip]$ sh ./zip.sh 
bool(true)
int(800)
bool(true)
int(876)



Actual result:
--------------
[mas@www zip]$ sh ./zip.sh 
bool(true)
int(800)
int(5)
int(0)
