Description:
------------
Was successfully running 7.0RC1 so switched to trunk/master

I consistently get this warning about wrong size calculations

php-fpm using opcache

WARNING: [pool www] child 32223 said into stderr: "Thu Sep  3 11:40:47 2015
 (32223): Warning Internal error: wrong size calculation: 
compat.php start=0x06121740, end=0x06124f18, real=0x06124ef8"

WARNING: [pool www] child 32223 said into stderr: "Thu Sep  3 11:40:47 2015
 (32223): Warning Internal error: wrong size calculation: l10n.php start=0x061e5900, end=0x061e7a50, real=0x061e7a30"

Happens on the same two files consistently, even after a restart.

This appears to be the same problem as Bug #69838 from June-15-2015 which seems to have been patched but maybe not fixed entirely?

could you please paste the two files out here？
 [2015-09-04 08:46 UTC] ck+php dot net at bbshowcase dot org 
Given their size, how about just direct text links:

http://svn.automattic.com/bbpress/tags/0.9.0.7/bb-includes/l10n.php

http://svn.automattic.com/bbpress/tags/0.9.0.7/bb-includes/compat.php

(I don't see anything special about them but maybe you know better)

I should also note, the error only happens ONCE upon php-fpm restart, perhaps when those two scripts are put into the cache the first time?

If I restart php-fpm I can consistently reproduce the error.

The start/end/real numbers change of course.

Maybe somewhat relevant it is in an openvz vps container but in theory that should not affect php?

Happy to test any patch you'd like to try.

I also see this bug with 7.0.0RC2 x64 TS + Apache/2.4.16 x64 on Windows 10 x64

Error message is shown only on some certain PHP scripts, not all of them. Here is a part of Apache log:

@"ck+php dot net" #69838 is similar, but this one looks like have been caused by some change after it. Please check now.

Thanks.

Could you give me a download link to latest master build for win x64 so I can also verify if the problem is gone.
 [2015-09-09 16:42 UTC] cmb@php.net 
You can download Windows snapshots from
<http://windows.php.net/snapshots/#php-master> or
<http://windows.php.net/downloads/snaps/master/>.

I tested with build php-master-ts-windows-vc14-x64-re0f390c

With 7.0.0RC2 Opcache produced internal error:wrong size calculation on some PhpMyAdmin php-scripts.

Now, with this master build, phpmyadmin causes Apache to crash.
Other PHP scripts seems to work as expected.
When I go back to 7.0.0RC1, PhPMyAdmin runs fine.

Pasted from event log:

Tested again with build php-master-ts-windows-vc14-x64-re0f390c.
This time OpCache was disabled.
Same result with PhpMyAdmin, Apache httpd crashed.
All other PHP applications run as expected.
Strange.
