You either have to increase the stack size or tune pcre.recursion_limit and pcre.backtrack_limit properly. Previous Comments: ------------------------------------------------------------------------ [2009-05-06 21:11:12] raul dot gigea at directmedia dot de I already wrote that my stacksize was 64 MB. ulimit -s 1024 would reduce it to only 1 MB. 64MB is the upper limit without recompiling the kernel. And i don't think that this specific regex should eat up 64 MB of stack size ... Anyway, here's the result: % ulimit -s 1024 % ulimit -s 1024 % ./sapi/cli/php ~/test.php zsh: segmentation fault (core dumped) ./sapi/cli/php ~/test.php % ulimit -s 65535 % ulimit -s 65535 % ./sapi/cli/php ~/test.php zsh: segmentation fault (core dumped) ./sapi/cli/php ~/test.php % ulimit -s 65537 ulimit: value exceeds hard limit ------------------------------------------------------------------------ [2009-05-06 20:53:44] j...@php.net You need to increase the stack size. I tried with 'ulimit -s 1024' and that does not crash.. ------------------------------------------------------------------------ [2009-05-06 20:44:58] raul dot gigea at directmedia dot de Ok, i tried using the CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz Which by the way was only 1 day newer than the one I tried. I used your configure line: 'configure' \ '--disable-all' \ '--enable-debug' \ '--disable-reflection' \ '--disable-cgi' \ '--with-curl' \ '--with-curlwrappers' \ '--with-pcre-regex' \ '--with-mhash' And its still segfaulting ------------------------------------------------------------------------ [2009-05-06 18:37:28] j...@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ I can not reproduce this with linux and latest PHP_5_2 snapshot using this configure line: '/usr/src/php-5.2CVS/configure' \ '--disable-all' \ '--enable-debug' \ '--disable-reflection' \ '--disable-cgi' \ '--with-curl' \ '--with-curlwrappers' \ '--with-pcre-regex' \ '--with-mhash' ------------------------------------------------------------------------ [2009-05-05 18:36:26] f...@php.net verified with FreeBSD 7.1-RELEASE-p4 and current snapshot: "Segmentation fault: 11 (core dumped)" Although I didn't examine the coredump in detail HEAD works fine ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
