Bug #63840 [NEW]: preg_peplace crash

From: DuMOHsmol at yandex dot ru Operating system: Windows PHP version: 5.3Git-2012-12-23 (snap) Package: *Regular Expressions Bug Type: Bug Bug description:preg_peplace crash Description: ------------ Hello, this code crashes Apache with PHP on Windows. I know that this regex is not quite correct, but still. The solution is to increase Apache stack, but I think there should be some check in PHP to prevent crashing. Test script: --------------- $text = ' test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test test_test_test_test_test_test_test_test_test_test_test_test_test_test_test '; $text = preg_replace('/([\n]|.)*/','test',$text); echo $text; -- Edit bug report at https://bugs.php.net/bug.php?id=63840&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63840&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63840&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63840&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63840&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63840&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63840&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63840&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63840&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63840&r=support Expected behavior: https://bugs.php.net/fix.php?id=63840&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63840&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63840&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63840&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63840&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63840&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63840&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63840&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63840&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63840&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63840&r=mysqlcfg
