#33357 [NEW]: require_once randomly fails to include file

From: elite at programmer dot net Operating system: Windows 2003 SP1 PHP version: 5.0.4 PHP Bug Type: Zend Engine 2 problem Bug description: require_once randomly fails to include file Description: ------------ When using require_once("file.php") to include "file.php" in multiple files, files which are included in each another on several levels, require_once("file.php") randomly fails to include the file at all. Most of the time it includes it, but sometimes it will just fail and the system will come to a halt since that file is vital. Changing to require("file.php") works, but obviously this would include the file several times. Reproduce code: --------------- inc.php $dsn = 'mssql://user:pass@localhost/database'; $db = DB::connect($dsn); if( PEAR::isError( $db ) ) { die "Database connect failed"; } file1.php: require_once("inc.php"); file2.php require_once("file1.php"); require_once("inc.php"); Expected result: ---------------- inc.php included once every timed Actual result: -------------- inc.php sometimes is not included at all, since the database connection in inc.php is not initialized and $db is NULL -- Edit bug report at http://bugs.php.net/?id=33357&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33357&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33357&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33357&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33357&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33357&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33357&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33357&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33357&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33357&r=support Expected behavior: http://bugs.php.net/fix.php?id=33357&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33357&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33357&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33357&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33357&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33357&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33357&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33357&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33357&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33357&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33357&r=mysqlcfg
