#32781 [NEW]: session_start() outputs newline character when complex object used in session

From: douglas dot day at calendarsystems dot com Operating system: WinXP PHP version: 5.0.3 PHP Bug Type: Session related Bug description: session_start() outputs newline character when complex object used in session Description: ------------ I assign a complex object as a session variable, then the next time session_start() is called, it outputs a newline character (which should never happen). If I don't assign this object as a session variable, session_start() functions normally. Any other action I've taken with $_SESSION produces the same results, unless I assign the complex object. Reproduce code: --------------- // Page 1 $_SESSION["var"] = new MyComplexObject(); // Page 2 ob_start(); $len_before = ob_get_length(); session_start(); $len_after = ob_get_length(); ob_end_flush(); echo $len_before . "," . $len_after; Expected result: ---------------- Output: 0,0 Actual result: -------------- Output: [newline] 0,2 -- Edit bug report at http://bugs.php.net/?id=32781&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32781&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32781&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32781&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32781&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32781&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32781&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32781&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32781&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32781&r=support Expected behavior: http://bugs.php.net/fix.php?id=32781&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32781&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32781&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32781&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32781&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32781&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32781&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32781&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32781&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32781&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32781&r=mysqlcfg
