#30777 [NEW]: Apache/PHP/DB3/DB4/Subversion causes repeatable segfault

From: shire at tekrat dot com Operating system: Linux Slackware PHP version: 4.3.9 PHP Bug Type: Apache related Bug description: Apache/PHP/DB3/DB4/Subversion causes repeatable segfault Description: ------------ I've noticed segfaults occuring both on the initial call of any php file or on the imap_open call, although the nature of the code/call seems to be irrelevent to the actual problem. It becames apparent that the PHP/Apache/Subversion/DB3/DB4 combination becomes a problem. Even with PHP/Apache/Subversion compiled with DB4, if a DB3.so is added to the system, then php/apache will begin to segfault. This has been observed in php4.3.8 (faults on any php script) and php4.3.9(fault on imap_open). it appears that php will try and load any db library it finds, rather than the latest module ie: db4 over db3. This apparently causes a conflict/segfault in php/apache. Reproduce code: --------------- You can reproduce this by compiling php/apache/subversion with DB4(required by subversion) and then adding db3.so to the system. Expected result: ---------------- n/a -- Edit bug report at http://bugs.php.net/?id=30777&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30777&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30777&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30777&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30777&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30777&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30777&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30777&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30777&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30777&r=support Expected behavior: http://bugs.php.net/fix.php?id=30777&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30777&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30777&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30777&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30777&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30777&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30777&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30777&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30777&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30777&r=mysqlcfg
