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 this bug report at https://bugs.php.net/bug.php?id=69464&edit=1
