I had the same problem. I am not sure if the GNU debugger looks at the
.pdb files, but that does not seem to make a difference.

Maybe the developers of OPcache can do something with this information,
although it is deep inside Windows. Is it a Windows Server? Which
edition? 2008 R2 or higher?

Your bug report was talking about
C:\Windows\SysWOW64\ntdll.dll

Mixup of 64-bits and 32-bits?

How do I contact them? Actually, this is Windows 7 Professional Service Pack 1.
I can test on a Server 2008 R2 machine (which is what we use in production), if
that would help.

Now, that is very odd. Why would gdb32.exe (or php.exe 32 bit in this context)
be accessing C:\Windows\system32\ntdll.dll?

You've got a really weird problem at hand. If even 'php -r exit();'
crashes, there definitely is something wrong with your setup. Did you
load php_opcache.dll with
zend_extension=php_opcache.dll (no path=it looks in your extension_dir)
And did you have the recommended opcache.xxx settings as stated at the
bottom of https://github.com/zendtech/ZendOptimizerPlus
To rule out other factors, I would disable all extensions except opcache
and then try php -r exit(); once again.

I will, but 2 things that really confuse me:
* we have one machine (out of 4) that does not crash - all of these machines
are built and configured to a specification, so I don't know why this one is
different
* the error does not occur when in IIS - only on the CLI

We have been loading the extension as such:
zend_extension="c:/php/ext/php_opcache.dll"
However, I've tried it the other way as well:
zend_extension=php_opcache.dll
Still crashes.
Yes, we are using those recommended settings.
Ahhhh, geez. It looks like it's caused by Wincache. I disable and enable that
extension and the crashing stops and starts.
However, again, I've tested Wincache thoroughly with Opcache in IIS and have no
issues. It's only on the command line.

Where did you get the php_wincache.dll? I could not find it on PHP.net
and neither on http://www.iis.net/downloads/microsoft/wincache-extension
Did you compile it yourself? It might be worth a try to use the
php_wincache.dll from one of my builds:
