ID: 34260 User updated by: etnu at etnu dot org Reported By: etnu at etnu dot org -Status: Feedback +Status: Open Bug Type: Class/Object related Operating System: Debian 3.1 (Sarge) PHP Version: 5CVS-2005-08-25 (snap) New Comment:
Hi, I don't have the extra machine to test this one out on, unfortunately, and I can't seem to get gdb to compile on this particular platform. I can confirm that the code I posted also causes seg faults on xeons (both dual & single) running Sarge 3.1 (these are production boxes, so I can't put the debugger on here to test it), and causes fatal exceptions on windows. All of these tests were conducted running under apache. It also seg faults in CLI mode, though, which lead me to believe that the problem is fundamentally tied to the implementation of __call and / or the callback mechanism rather than any platform-specific issues. Sorry I couldn't provide more details than that. Previous Comments: ------------------------------------------------------------------------ [2005-08-26 08:57:29] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2005-08-25 22:03:06] etnu at etnu dot org Description: ------------ A segfault occurs when using callbacks to functions that get triggered via __call. In the case of what's actually being called, the class is derived from mysqli. I haven't done extensive testing, but I was getting segfaults with both array_map and array_filter. It seems to be a general callback-related issue. Dual Opteron Kernel is SMP + 64bit Configure: ./configure \ --with-pgsql \ --with-xmlrpc \ --with-apxs2=/usr/local/apache2/bin/apxs \ --with-mysql=/usr --with-mysqli=/usr/bin/mysql_config \ --prefix=/usr/local/apache2/php \ --with-config-file-path=/usr/local/apache2/php \ --enable-force-cgi-redirect \ --disable-magic-quotes \ --with-curl \ --with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-freetype-dir=/usr/lib --with-zlib-dir=/usr/lib Reproduce code: --------------- <?php class Faulty { function __call($Method,$Args) { switch($Method) { case 'seg': echo "I hate me"; break; } } function NormalMethod($Args) { echo "I heart me"; } } $Faulty = new Faulty(); $Array = array('Some junk','Some other junk'); // This causes a seg fault. $Failure = array_map(array($Faulty,'seg'),$Array); // This does not. $Failure = array_map(array($Faulty,'NormalMethod'),$Array); ?> Expected result: ---------------- Not seg faulting. Actual result: -------------- Segfaulting. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34260&edit=1
