From: test_junk at hotmail dot it Operating system: linux 2.4 i386 PHP version: 4.4.5 PHP Bug Type: PCRE related Bug description: pcrelib broken with php 4.4.5
Description: ------------ Recent update to php 4.4.5 broke PCRE regex support. The issue showed up upgrading to 4.4.5 installed as apache module (1.3.37 both on 2.4 and 2.6 kernels) and was resolved downgrading back to 4.4.4 I could trigger a segfault with several applications but I was not able to detect the chunk of php code responsible of it. Actual result: -------------- segfault... #0 match (eptr=0x0, ecode=0x0, offset_top=0, md=0x0, ims=0, eptrb=0x0, flags=0, rdepth=0) at /sources/php-4.4.5/ext/pcre/pcrelib/pcre_exec.c:517 Cannot access memory at address 0xbf7fff30 -- Edit bug report at http://bugs.php.net/?id=40624&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40624&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40624&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40624&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40624&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40624&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40624&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40624&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40624&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40624&r=support Expected behavior: http://bugs.php.net/fix.php?id=40624&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40624&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40624&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40624&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40624&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40624&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40624&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40624&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40624&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40624&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40624&r=mysqlcfg
