#41148 [NEW]: PHP 4.4.6 Segfault with PCRE 7.0 not with 6.6

From: baco at infomaniak dot ch Operating system: Linux/Debian PHP version: 4.4.6 PHP Bug Type: PCRE related Bug description: PHP 4.4.6 Segfault with PCRE 7.0 not with 6.6 Description: ------------ After upgrading PHP from 4.4.4 to 4.4.6 our customers using SPIP, Joomla Mambot, etc. their websites display a blank page or 500 due to a segfault of PHP. I have backported PCRE from version 7.0 to 6.6 on PHP 4.4.6. No more segfault of PHP and SPIP works as before. http://www.infomaniak.ch/php4/php-4.4.6-downgrade_pcre.patch http://www.infomaniak.ch/php4/ Best Regards, Guy Baconniere <baco(A-T)infomaniak.ch> REFERENCES http://www.guiderdoni.net/Probleme-Spip-et-php-version-4-4-6.html http://bugs.php.net/bug.php?id=41050 Reproduce code: --------------- 1. Compile PHP 4.4.6 without my patch 2. install any version of SPIP including 1.9.2 (http://www.spip.net) N.B. Only 1.9.2a has a workaround see http://trac.rezo.net/trac/spip/changeset/8844 I understand this maybe a bug in PCRE 7.0 (see bug #41050) but why do you not downgrade to 6.6 until fixed so your last PHP 4.4.x will be again more "stable" ? Expected result: ---------------- SPIP working. Actual result: -------------- Blank page, HTTP 500, segfault of PHP. -- Edit bug report at http://bugs.php.net/?id=41148&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41148&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41148&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41148&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41148&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41148&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41148&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41148&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41148&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41148&r=support Expected behavior: http://bugs.php.net/fix.php?id=41148&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41148&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41148&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41148&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41148&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41148&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41148&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41148&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41148&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41148&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41148&r=mysqlcfg
