OPcache settings: opcache.enable_cli=1 opcache.file_cache=/var/tmp/php/opcache opcache.file_cache_only=1 All scripts run fine, however test script crashes after execution. In addition, no problem occurs with same script on Linux. Test script: --------------- <?php $sum = array(); // No segv if commented out this line $sum[0] = 0; var_dump($sum); Expected result: ---------------- array(1) { [0]=> int(0) } Actual result: -------------- array(1) { [0]=> int(0) } Segmentation fault: 11 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70843&edit=1
