I have tried to download php-5.6-nts-windows-vc11-x86-r052dd30.zip and it seems that the file is
corrupted (the size is only 48 kb).

Thanks for the checks. However you took too early snapshot. You need one from October 4th or later.
With NTS you say, looks like this one could suffice http://windows.php.net/downloads/snaps/php-5.6/r052dd30/
Thanks.

I have tried to reproduce this bug in snapshot r07a8e5c (I am unable to download later snapshot) and
the bug persists.
Additional info:
I use non-threadsafe version of PHP (as expected with using mod_fcgid plugin).

Thanks for the report. Could you please check some latest 5.6 snapshot? http://windows.php.net/downloads/snaps/php-5.6/
Thanks.

Description:
------------
The opcache accesses to invalid address. PHP is running via Apache using mod_fcgid. Php.ini does not
contain any plugins (except opcache).
Eventlog message:
The description for Event ID 487 from source Zend OPcache cannot be found. Either the component that
raises this event is not installed on your local computer or the installation is corrupted. You can
install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Unable to reattach to base address
Pokus o pÅÃstup k nepÅÃpustné adrese. (translation: A try to access to invalid
address)
I have run the attached test script using utility ab.exe:
ab.exe -n 50 -c 3 http://myip/attachedscript.php
This bug is observed in versions 5.6.11-14. Version 5.6.10 seems to work correctly.
Test script:
---------------
<?php
$sec = 3;
echo "waiting $sec s...";
for($i=0; $i < $sec; ++$i) {
sleep(1);
}
echo "end<br>";
echo "The script has waited for $sec sec";
