Bug #60266 [Opn->Bgs]: Stack overflow makes PHP crash with Segmentation Fault

Edit report at https://bugs.php.net/bug.php?id=60266&edit=1 ID: 60266 Updated by: johannes@php.net Reported by: smh at wannafind dot dk Summary: Stack overflow makes PHP crash with Segmentation Fault -Status: Open +Status: Bogus Type: Bug Package: Reproducible crash Operating System: Linux 2.6.18-194.26.1.el5 PHP Version: 5.4.0RC1 Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php You're having an infinite recursion. This recursion leads to an stack overflow. This causes the operating system to terminate the process. Nothing PHP can fix. Previous Comments: ------------------------------------------------------------------------ [2011-11-11 13:14:34] smh at wannafind dot dk Description: ------------ Whenever a PHP script encounters a stack overflow, it just dies with a message to stderr stating: "Segmentation fault". Test script: --------------- #!/usr/local/bin/php <?php function segmentationFaultFunction() { static $counter; echo ++$counter . ' '; $func = function(){ return segmentationFaultFunction(); }; $func->__invoke(); return $func; } $function = segmentationFaultFunction(); $function->__invoke(); echo 'Done, no segmentation faults' . PHP_EOL; Expected result: ---------------- I expected my error handler to be called with a stack trace. The best solution would be if PHP registers the error before crashing and throws an exception with the stack trace. The second best solution would be if PHP could give us a better error description than Segmentation fault. Maybe just terminate the script with an error that looks like this: "Stack overflow in file: /scripts/test.segfault.php on line 10". Actual result: -------------- Script terminates with an uncatchable error to stdout: "Segmentation fault". ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60266&edit=1
