PHP Version: 5.5.0RC2 OS: Windows 7 Pro 64-Bit
Private report: No CVE-ID:
 [2013-05-27 06:53 UTC] gertrainer dot bitterlich at ima-dresden dot de
If I use php-5.5.0RC2-nts-Win32-VC11-x64, I get the following error messages.
With PHP 5.5RC2 32-Bit there is no error.

HTTP-Fehler 500.0 - Internal Server Error

Application Event-Log-Error message:
- <Event xmlns="">
- <System>
  <Provider Name="Zend OPcache" /> 
  <EventID Qualifiers="0">487</EventID> 
  <TimeCreated SystemTime="2013-05-27T06:27:21.000000000Z" /> 
  <Security /> 
- <EventData>
  <Data>Unable to reattach to base address</Data> 
  <Data>Es wurde versucht, auf eine unzulässige Adresse zuzugreifen.</Data> 

This is allways in connection with PHP scripts, witch are called over AJAX requests.

If I deactivate OPCache in the php.ini, then it works correct.

Thank you for the answer.
If I use in the php.ini
  opcache.mmap_base = 0x20000000
then it works without error.

Link to Zend's page is bad, here is the correct link:

I'm having the same problem, but it's with 5.5.9 (or 5.5.8) and VC11-NTS 32-Bit.
