Bug #72948 [NEW]: Uncatchable "Catchable" fatal error for class to string conversions

From: fredrik at neam dot se Operating system: linux PHP version: 7.1.0beta3 Package: *Programming Data Structures Bug Type: Bug Bug description:Uncatchable "Catchable" fatal error for class to string conversions Description: ------------ When attempting to convert a class to a string, the resulting "Catchable" fatal error is not being caught. This results in confusion regarding whether or not PHP7's new ability to catch these fatal errors work or not. It turns out that some catchable fatal errors indeed can be caught, while some don't, like the one being reported here. This has been confirmed using the below test script against all active php and hhvm versions: https://3v4l.org/GeNpF Test script: --------------- <?php echo "PHP Version: " . PHP_VERSION . "\n"; try { $v = new DateTime(); $v = (string) $v; } catch (Error $e) { echo "Caught 'Catchable fatal error' with message: " . $e->getMessage(); die(); } echo "Did not catch 'Catchable fatal error'"; Expected result: ---------------- The Catchable fatal error should be caught Actual result: -------------- The Catchable fatal error is acting like a non-catchable fatal error -- Edit bug report at https://bugs.php.net/bug.php?id=72948&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72948&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72948&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72948&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72948&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72948&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72948&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72948&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72948&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72948&r=support Expected behavior: https://bugs.php.net/fix.php?id=72948&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72948&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72948&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72948&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72948&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72948&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72948&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72948&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72948&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72948&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72948&r=mysqlcfg
