#34216 [Asn->Fbk]: Segfault with autoload

ID: 34216 Updated by: tony2001@php.net Reported By: sebastian@php.net -Status: Assigned +Status: Feedback Bug Type: SPL related Operating System: Linux PHP Version: 5.1.0RC1 Assigned To: helly New Comment: Sebastian, I'd appreciate if you provide a complete reproduce case (doesn't matter which size it is). Previous Comments: ------------------------------------------------------------------------ [2005-08-23 07:27:09] sebastian@php.net Description: ------------ I am experiencing a segfault with spl_autoload in the PHP_5_1 branch with the upcoming PHPUnit 2.3.0. The nature of PHPUnit's complexity makes it almost impossible for me to come up with a simple, reproducing script (I already invested hours into this, to no avail so far). It is weird that the segfault only occurs in one out of two common code paths of PHPUnit's TextUI test runner. Furthermore, small code changes (see below) seem to make the problem go away: Reproduce code: --------------- Segfault: function PHPUnit2_Util_Classloader($className) { print "Loading $className.\n"; if (strpos($className, 'PHPUnit2_') !== FALSE) { @include(str_replace('_', '/', $className) . '.php'); } } spl_autoload_register('PHPUnit2_Util_Classloader'); Segfault: function PHPUnit2_Util_Classloader($className) { $bt = debug_backtrace(); print "Loading $className.\n"; if (strpos($className, 'PHPUnit2_') !== FALSE) { @include(str_replace('_', '/', $className) . '.php'); } } spl_autoload_register('PHPUnit2_Util_Classloader'); No Segfault: function PHPUnit2_Util_Classloader($className) { $bt = debug_backtrace(); print_r($bt[1]); print "Loading $className.\n"; if (strpos($className, 'PHPUnit2_') !== FALSE) { @include(str_replace('_', '/', $className) . '.php'); } } spl_autoload_register('PHPUnit2_Util_Classloader'); Actual result: -------------- Below are the links to the results of GDB and Valgrind. Interestingly, when run through GDB it segfaults, when run through Valgrind it does not segfault.
