#48634 [NEW]: Calling ob_get_flush() inside an output handler causes crashes

From: gwynne@php.net Operating system: Darwin9 (MacOS X 10.5) PHP version: 5.3CVS-2009-06-22 (CVS) PHP Bug Type: Reproducible crash Bug description: Calling ob_get_flush() inside an output handler causes crashes Description: ------------ The subject kind of says most of it. Under both GDB and Valgrind, PHP enters a massive recursion until it finally crashes by overrunning the stack, which is expected, according to a comment in a test that a fix needs to be backported from HEAD. So this bug is mostly about "please backport this fix", I suppose. Reproduce code: --------------- See tests/output/ob_11.phpt Expected result: ---------------- A fatal error saying "you can't do that". Actual result: -------------- Endless recursion. -- Edit bug report at http://bugs.php.net/?id=48634&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48634&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48634&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48634&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48634&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48634&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48634&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48634&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48634&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48634&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48634&r=support Expected behavior: http://bugs.php.net/fix.php?id=48634&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48634&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48634&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48634&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48634&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48634&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48634&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48634&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48634&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48634&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48634&r=mysqlcfg
