Bug #69363 [NEW]: eval()ed string literal is not intened on PHP7+OPcache

From: for-bugs at hnw dot jp Operating system: any PHP version: master-Git-2015-04-03 (Git) Package: opcache Bug Type: Bug Bug description:eval()ed string literal is not intened on PHP7+OPcache Description: ------------ On PHP7 without OPcache, eval('$bar="baz"') makes interned string. However, eval()ed string literal is dynamically allocated with OPcache enabled. The interned string on PHP7 is not refcounted. So, string refcount(2) means non-interned. Test script: --------------- <?php $foo="baz"; $eval_str='$bar="baz";'; eval($eval_str); debug_zval_dump($foo); debug_zval_dump($bar); Expected result: ---------------- string(3) "baz" refcount(1) string(3) "baz" refcount(1) Actual result: -------------- string(3) "baz" refcount(1) string(3) "baz" refcount(2) -- Edit bug report at https://bugs.php.net/bug.php?id=69363&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69363&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69363&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69363&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69363&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69363&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69363&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69363&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69363&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69363&r=support Expected behavior: https://bugs.php.net/fix.php?id=69363&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69363&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69363&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69363&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69363&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69363&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69363&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69363&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69363&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69363&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69363&r=mysqlcfg
