Bug #77743 [NEW]: Random evaluation

From: houman dot bakhtiari at groupe-gts dot fr Operating system: Debian (test on docker FPM 7.3) PHP version: 7.2.16 Package: opcache Bug Type: Bug Bug description:Random evaluation Description: ------------ Here is a bug coming from OPCACHE (I think because doesn't appears when disabled). Random evaluation of a variable when OPCACHE is activated. At first run I obtain "bool(false) bool(false) bool(false) bool(false)", After some refresh I always obtain "bool(true) bool(true) bool(true) bool(true)". This bug doesn't appear when all the scripts are in the same file. The bug exists on all 7.2.x and 7.3.x. Test script: --------------- test.php : === <?php require 'test2.php'; function myRet(){ return 45; } $toto = new Toto(); $toto->process1(); ----------------------- test2.php : === <?php class Toto { public function process1() { $array_error = []; $keep_products = [1, 2, 3, 4]; foreach ($keep_products as $k => $v) { $id_country = myRet(); if ($id_country === false && false) { } var_dump($id_country === false); } } } --------------------- Dockerfile : === FROM php:7.2.0-fpm-alpine RUN docker-php-ext-install opcache WORKDIR /var/www EXPOSE 9000 CMD ["php-fpm"] Expected result: ---------------- bool(false) bool(false) bool(false) bool(false) Actual result: -------------- after fome refresh : bool(true) bool(true) bool(true) bool(true) -- Edit bug report at https://bugs.php.net/bug.php?id=77743&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77743&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77743&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77743&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77743&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77743&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77743&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77743&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77743&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77743&r=support Expected behavior: https://bugs.php.net/fix.php?id=77743&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77743&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77743&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77743&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77743&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77743&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77743&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77743&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77743&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77743&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77743&r=mysqlcfg
