Bug #72112 [NEW]: Opcache corruption after opcache_reset()

From: thomas dot colomb at dailymotion dot com Operating system: Ubuntu 14.04 PHP version: 7.0.5 Package: opcache Bug Type: Bug Bug description:Opcache corruption after opcache_reset() Description: ------------ After calling opcache_reset() function we encounter some weird errors. It happens randomly on servers (10 of 400 servers production) Some letter a replaced by others, Class seems to be already declared.. etc Example of errors triggered after opcache_reset(): * Unknown column 'saken' in 'field list' => in this example t is replaced by s in the sql query. This can be really a big problem if in example on an update query a w of where is replaced by a ; and this will update whole table * PHP Fatal error: Cannot declare class ZZZZZ, because the name is already in use in /dir/dir/z.php on line 0 * PHP Fatal error: Class XXX contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (YYY::funczzz) in /dir/dir/x.php on line 20 * PHP Fatal error: Uncaught Error: Call to undefined method XXX::func1() in /dir/dir/x.php:218 It seems related to #71574 but it's still not corrected. php -v PHP 7.0.5-2+deb.sury.org~trusty+1 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies x@server:~# lsb_release --id Distributor ID: Ubuntu x@server:~# lsb_release -r Release: 14.04 -- Edit bug report at https://bugs.php.net/bug.php?id=72112&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72112&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72112&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72112&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72112&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72112&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72112&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72112&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72112&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72112&r=support Expected behavior: https://bugs.php.net/fix.php?id=72112&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72112&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72112&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72112&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72112&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72112&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72112&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72112&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72112&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72112&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72112&r=mysqlcfg
