Bug #69740 [NEW]: finally in generator (yield) swallows exception in iteration

From: markus at malkusch dot de Operating system: Linux PHP version: 5.6.9 Package: Scripting Engine problem Bug Type: Bug Bug description:finally in generator (yield) swallows exception in iteration Description: ------------ From https://wiki.php.net/rfc/generators I learned that finally blocks are valid in Generators: > If the generator contains (relevant) finally blocks those will be run. When I iterate over such a generator and would throw an exception the exception seems to be swallowed. This behaviour was introduced in PHP-5.6 as it worked in PHP-5.5 as I would expect it: http://3v4l.org/QX4qP I can't tell if this is related to https://bugs.php.net/bug.php?id=62210. Test script: --------------- <?php function generate() { try { yield 1; yield 2; } finally { echo "finally\n"; } } foreach (generate() as $i) { echo $i, "\n"; throw new Exception(); } Expected result: ---------------- 1 finally Fatal error: Uncaught exception 'Exception' Actual result: -------------- 1 finally -- Edit bug report at https://bugs.php.net/bug.php?id=69740&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69740&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69740&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69740&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69740&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69740&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69740&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69740&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69740&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69740&r=support Expected behavior: https://bugs.php.net/fix.php?id=69740&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69740&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69740&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69740&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69740&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69740&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69740&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69740&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69740&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69740&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69740&r=mysqlcfg
