#31119 [Opn->Fbk]: php crashes apache2 child and chrashes in interactive mode

ID: 31119 Updated by: sniper@php.net Reported By: shoorik at ilyichevsk dot net -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: * (ZTS only!) PHP Version: 4.3.10, 5.0.3 New Comment: Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report.

As I wrote above - I could not repeat this bug anywhere else - all other sites works fine. ------------------------------------------------------------------------ [2004-12-16 15:41:39] shoorik at ilyichevsk dot net In addition. 5.0.3 has the same behaviour. Crash in interactive mode and web requests on phpMyAdmin/index.php What is interesting - with almost sam backtrace... Program received signal SIGSEGV, Segmentation fault. 0x081b74a3 in execute (op_array=0x83af30c, tsrm_ls=0x821a1f0) at /usr/local/src/php-5.0.3/Zend/zend_execute.c:1400 1400 if (EX(opline)->handler(&execute_data, EX(opline), op_array TSRMLS_CC)) { (gdb) bt #0 0x081b74a3 in execute (op_array=0x83af30c, tsrm_ls=0x821a1f0) at /usr/local/src/php-5.0.3/Zend/zend_execute.c:1400 #1 0x0818efaf in execute_new_code (tsrm_ls=0x821a1f0) at /usr/local/src/php-5.0.3/Zend/zend_execute_API.c:1074 #2 0x08177a9c in zendparse (tsrm_ls=0x821a1f0) at Zend/zend_language_parser.c:2359 #3 0x0817b9aa in compile_file (file_handle=0xbfbfc000, type=8, tsrm_ls=0x821a1f0) at Zend/zend_language_scanner.c:3142 #4 0x081bcfbb in zend_include_or_eval_handler (execute_data=0xbfbfc090, opline=0x831500c, op_array=0xa, tsrm_ls=0x821a1f0) at /usr/local/src/php-5.0.3/Zend/zend_execute.c:3517 #5 0x081b74a5 in execute (op_array=0x821bf0c, tsrm_ls=0x821a1f0) at /usr/local/src/php-5.0.3/Zend/zend_execute.c:1400 #6 0x0818efaf in execute_new_code (tsrm_ls=0x821a1f0) at /usr/local/src/php-5.0.3/Zend/zend_execute_API.c:1074 #7 0x08177a9c in zendparse (tsrm_ls=0x821a1f0) at Zend/zend_language_parser.c:2359 OK! I give up! Will try to figure out what call\syntax causes exactly system crash and post there if something. ------------------------------------------------------------------------ [2004-12-16 13:16:57] shoorik at ilyichevsk dot net Prefork mpm works nice, but I must solve few issues with CGI zombies using threads that way. Thats why I tried to use worker mpm. Anyway - there is few sites which still work on threaded php - I got this crash only with phpMyAdmin (still trying to find out WHERE?). So I must not use thread features anyway... Sadly... Will PHP team fix this is fuftre anyway? Perl story reproduces? ------------------------------------------------------------------------ [2004-12-16 13:04:03] sniper@php.net Does it crash if you compile Apache with prefork mpm ?? ie. don't even try to use threading with php, it doesn't work. ------------------------------------------------------------------------ [2004-12-16 12:29:55] shoorik at ilyichevsk dot net Description: ------------ Apache httpd-2.0.52 config: configure --prefix=/usr/local/apache --enable-suexec --enable-ext-filter --enable-rewrite --enable-ssl --with-mpm=worker --enable-threads NOTE: apache built with worker MPM!

Requests to phpMyAdmin using web causes apache chield to die with signal 11. .... [Thu Dec 16 10:51:52 2004] [notice] child pid 69976 exit signal Illegal instruction (4) .... Crash also could be reproduced in cmd line using "php -a index.php" command. But in non-interactive mode (without -a option) it works. Backtrace see below This crash also reproducible with PHP-4.3.6 using same configureaion. 4.3.6 crashes with the same backtrace.
