From: gross at schlund dot de Operating system: Linux PHP version: 4.3.6 PHP Bug Type: Zend Engine 2 problem Bug description: php crashes with big scripts
Description: ------------ Giving it a large script, PHP 4.3.6 crashes during parsing it. The stacktrace is as follows: (gdb) bt #0 0x081a5be6 in execute (op_array=0x8322c3c) at /usr/src/kundenserver/php-4.3.6/Zend/zend_execute.c:2007 #1 0x08191598 in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /usr/src/kundenserver/php-4.3.6/Zend/zend.c:886 #2 0x0816a933 in php_execute_script (primary_file=0xbffffa38) at /usr/src/kundenserver/php-4.3.6/main/main.c:1731 #3 0x081a9fd3 in main (argc=2, argv=0xbffffab4) at /usr/src/kundenserver/php-4.3.6/sapi/cgi/cgi_main.c:1592 (gdb) You can find a core file under http://www.andigross.de/phpcrash/core.gz and the binary under http://www.andigross.de/phpcrash/phpbinary A phpinfo is under http://www.andigross.de/phpcrash/phpinfo.html the configure-line is: ./configure --with-zlib --enable-debug --enable-safe-mode=no --enable-discard-path=no --enable-track-vars --enable-force-cgi-redirect --enable-memory-limit --enable-trans-sid --enable-shmop --with-openssl --enable-xslt --with-xslt-sablot --with-dom --with-dom-xslt --with-dom-exslt The only modification to php.ini is: memory_limit = 90M; Compiler ist gcc 2.95.4. Reproduce code: --------------- You can find the code here: http://www.andigross.de/phpcrash/testdaten.php.txt Of curse, this is a very simple one to show the problem. The problem also occurs with "more useful" scripts. The application that caused the problem does something like $big_text="Huge PHP source"; eval($big_text); Expected result: ---------------- The script produces no output. With PHP 4.2.3 it works fine. Actual result: -------------- (gdb) bt #0 0x081a5be6 in execute (op_array=0x8322c3c) at /usr/src/kundenserver/php-4.3.6/Zend/zend_execute.c:2007 #1 0x08191598 in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /usr/src/kundenserver/php-4.3.6/Zend/zend.c:886 #2 0x0816a933 in php_execute_script (primary_file=0xbffffa38) at /usr/src/kundenserver/php-4.3.6/main/main.c:1731 #3 0x081a9fd3 in main (argc=2, argv=0xbffffab4) at /usr/src/kundenserver/php-4.3.6/sapi/cgi/cgi_main.c:1592 (gdb) -- Edit bug report at http://bugs.php.net/?id=28064&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28064&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28064&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28064&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28064&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28064&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28064&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28064&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28064&r=support Expected behavior: http://bugs.php.net/fix.php?id=28064&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28064&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28064&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28064&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28064&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28064&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28064&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28064&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28064&r=float
