Description:
------------
When php is running in fcgi mode ZipArchive::getStream() causes PHP to crash.

Test script:
---------------
<?
 $zip = new ZipArchive();
 $zip->open("/tmp/test.zip",ZIPARCHIVE::CREATE);
 $zip->addFromString("test.txt","This is a test");
 $zip->close();
 unset($zip);

 $zip2 = new ZipArchive();
 $zip->open("/tmp/test.zip");
 $fd = $zip->getStream("test.txt");  // CRASH
?>



Expected result:
----------------
Zip to return file handle.

Actual result:
--------------
PHP Crashes (webserver reports *498 recv() failed (104: Connection reset by peer) 
while reading response header from upstream) and returns 502 Bad Gateway...

I ever reproduce it in 5.3.10 but only several times. I can't reproduce it 
anymore.
   Can you provide more information about the bug? or try lastest version?

This does seem to be fixed in PHP 5.3.11 - it no longer crashes however :( now 
dba_fetch() crashes --- yay. On to another bug fixing fiesta!
