From: david at davidheath dot org Operating system: mandrake linux 10.1 PHP version: 4.3.11 PHP Bug Type: Reproducible crash Bug description: Segfault when using assignment by reference within function
Description: ------------ The attached program always segfaults. I have stripped out as much code as possible whilst ensuring that it still segfaults, I'm afraid I haven't been able to make the repro code any simpler. The problem is either something to do with the assignment by reference on line 11 in the test2::exists() method, or otherwise something to do with the use of unserialize(). I'm using the standard build of php4.3.11 with no special modules. Reproduce code: --------------- $ wget http://www.davidheath.org/php_bug/crash.php.txt $ wget http://www.davidheath.org/php_bug/testfile $ mv crash.php.txt crash.php $ php crash.php Expected result: ---------------- no segfault, no output at all Actual result: -------------- [EMAIL PROTECTED] dh]$ /usr/local/php4.3.11/bin/php.4.3.11 crash.php Content-type: text/html X-Powered-By: PHP/4.3.11 Segmentation fault (core dumped) When I run with debug build, it doesn't segfault: [EMAIL PROTECTED] dh]$ /usr/local/php4.3.11_debug/bin/php.4.3.11 crash.php Content-type: text/html X-Powered-By: PHP/4.3.11 /home/heathd/downloads/php-4.3.11/Zend/zend_execute.c(279) : Freeing 0x081EA8A4 (12 bytes), script=crash.php /home/heathd/downloads/php-4.3.11/Zend/zend_execute.c(282) : Freeing 0x081EA704 (28 bytes), script=crash.php /home/heathd/downloads/php-4.3.11/Zend/zend_variables.c(111) : Actual location (location was relayed) -- Edit bug report at http://bugs.php.net/?id=32685&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32685&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32685&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32685&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32685&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32685&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32685&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32685&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32685&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32685&r=support Expected behavior: http://bugs.php.net/fix.php?id=32685&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32685&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32685&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32685&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32685&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32685&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32685&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32685&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32685&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32685&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32685&r=mysqlcfg
