Bug #73067 [NEW]: __debugInfo crashes when throwing an exception

From: martin dot smeeckaert at gmail dot com Operating system: Ubuntu 16.04 PHP version: 7.0.10 Package: Reproducible crash Bug Type: Bug Bug description:__debugInfo crashes when throwing an exception Description: ------------ I'm using php 7.0.8 on Ubuntu 16.04 and I came across a strange bug, if an exception is thrown in the __debugInfo call, it will result in a fatal error no matter what you do. PHP expect __debugInfo to return an array but it is impossible because of the exception. Test script: --------------- <?php class Debug { public function __debugInfo() { throw new Exception("Test Crash"); } } try { var_dump(new Debug()); } catch (Exception $e) { echo $e->getMessage(); } Expected result: ---------------- > "Test Crash" Actual result: -------------- PHP Warning: Uncaught Exception: Test Crash in .../BugDebugInfo.php:7 Stack trace: #0 [internal function]: Debug->__debugInfo() #1 .../BugDebugInfo.php(12): var_dump(Object(Debug)) #2 {main} thrown in .../BugDebugInfo.php on line 7 PHP Fatal error: __debuginfo() must return an array in .../BugDebugInfo.php on line 12 -- Edit bug report at https://bugs.php.net/bug.php?id=73067&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73067&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73067&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73067&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73067&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73067&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73067&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73067&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73067&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73067&r=support Expected behavior: https://bugs.php.net/fix.php?id=73067&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73067&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73067&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73067&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73067&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73067&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73067&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73067&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73067&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73067&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73067&r=mysqlcfg
