From: berdir Operating system: Linux PHP version: master-Git-2015-04-15 (Git) Package: Scripting Engine problem Bug Type: Bug Bug description:Segfault in zend_hash_destroy() during shutdown Description: ------------ This is part of our efforts to get Drupal 8 green on PHP 7, see https://www.drupal.org/node/2454439. I've been trying to test with the latest PHP 7 build, but I'm now getting a lot of segfaults during the installer and running any web test. You can see the backtrace and code where it happens here: https://gist.githubusercontent.com/Berdir/f93e56c8a2643501ce51/raw/653fa8fea95d322f9f7836838177951db7fe57db/gistfile1.txt I'll try to bisect this down to a certain commit, but I had troubles the last time I tried to do something like that. Test script: --------------- To debug, get drupal and drush (from https://github.com/drush-ops/drush), then: gdb --args '/path/to/php7' '/path/to/drush.php' '--db-url=mysql://user:pass@localhost/db' 'si' '-y' 'standard' '-v' '-d' -- Edit bug report at https://bugs.php.net/bug.php?id=69464&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69464&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69464&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69464&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69464&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69464&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69464&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69464&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69464&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69464&r=support Expected behavior: https://bugs.php.net/fix.php?id=69464&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69464&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69464&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69464&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69464&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69464&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69464&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69464&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69464&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69464&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69464&r=mysqlcfg
