ID: 60627 Patch added by: larue...@php.net Reported by: fedora at famillecollet dot com Summary: httpd.worker segfault on startup Status: Analyzed Type: Bug Package: Apache2 related Operating System: GNU/Linux (Fedora 16) PHP Version: 5.4SVN-2011-12-30 (snap) Block user comment: N Private report: N New Comment: The following patch has been added/updated: Patch Name: bug60627.patch Revision: 1325663174 URL: https://bugs.php.net/patch-display.php?bug=60627&patch=bug60627.patch&revision=1325663174 Previous Comments: ------------------------------------------------------------------------ [2012-01-04 07:32:22] larue...@php.net hmm, the problem is when the real_value_hnd is called, the signal_startup has not been called yet... ------------------------------------------------------------------------ [2012-01-01 19:22:16] public at wernig dot net Just tried with 5.3.9RC4, and the problem does not occur. Seems to be something in 5.4 ------------------------------------------------------------------------ [2012-01-01 19:05:57] public at wernig dot net I have the same problem on Solaris 11 (express) i86pc. I'm not sure about ZTS mode (I have NOT set --enable-maintainer-zts) I have compiled php-5.4 (various versions, the latest one being 5.4.0RC4) with the following configure flags: --with-apxs2=/usr/local/apache2/bin/apxs --with-openssl=/usr/local/ssl --with-openssl-dir=/usr/local/ssl --with-zlib --enable-sockets --enable-shared=yes --enable-static=yes --prefix=/usr/local/apache2/php --enable-calendar --disable-ftp --with-mysql=/usr/local/mysql --with-imap=/usr/local/imap --with-imap-ssl=/usr/local/ssl --enable-flatfile --without-recode --disable-ipv6 --with-mysql-sock=/var/run/mysql/mysql.sock --with-gettext=/opt/csw --enable-libxml --with-db4=/usr/local/BerkeleyDB Builds and installs fine. But during apache (2.2.21) startup, it segfaults and dumps core: # /usr/local/svc/init.d/apache2 restart Restarting Apache2 httpd ... /usr/local/apache2/bin/apachectl: line 80: 17568: Memory fault(coredump) In fact, uncommenting all php_admin_value lines from apache config file, apache starts normally. When compiling and installing 5.3.6 with the same configure options, the problem does not occur. ------------------------------------------------------------------------ [2011-12-31 07:21:41] fedora at famillecollet dot com segfault occurs during apache config analyse. If config doesnt have any php_flag, php_value,... apache starts and works as expected. ------------------------------------------------------------------------ [2011-12-30 19:10:16] fedora at famillecollet dot com Description: ------------ With PHP build in ZTS mode, apache in worker mode segfault during launch Test script: --------------- $ gdb /usr/sbin/httpd.worker (gdb) run -X Expected result: ---------------- no error Actual result: -------------- (gdb) run -X ...
