From: dirk at bean-it dot nl Operating system: Debian 5.0 PHP version: 5.3.1 PHP Bug Type: Reproducible crash Bug description: Upgrading to php 5.3 > Application works but apache segfaults
Description: ------------ Upgrading to php 5.3 > Application works but apache segfaults I've upgraded from 5.2.11 to 5.3.1. Our application works fine when accessed from a browser, however the apache error log fills with messages like: [Fri Dec 04 11:24:59 2009] [notice] child pid 28025 exit signal Segmentation fault (11) Each request causes a message like this. This is not happening when using 5.2.11. I've tried to locate the problem by stepping through the code with the Zend debugger. Unfortunately, the problem does not occur when doing this. I've followed the instructions and created a backtrace (see below). The weird thing is, PHP compiled with --enable-debug, does not crash. I does give tons of "Memory leak" messages in the apache error.log. I'm not very in to this, so I hope this information gives somebody a clue. I've also tried a snapshot (5.3-200912040930), this doesn't work either, same segfaults. I'm more than happy to provide more info, test things, change things... Just let me know. ./configure options (I cannot reduce this set, the application will stop working) './configure' \ '--with-config-file-path=/etc' \ '--with-apxs2=/usr/bin/apxs2' \ '--with-gettext' \ '--with-libxml-dir=/usr/local' \ '--with-mysqli=/usr/bin/mysql_config' \ '--with-mcrypt' \ '--with-iconv' \ '--enable-mbstring' \ '--with-zlib=/usr' \ '--with-xsl' \ '--with-curl' \ '--with-gd' \ '--with-jpeg-dir=/usr/include' \ '--with-png-dir=/usr/include' \ '--with-openssl' \ '--with-freetype-dir' \ '--enable-gd-native-ttf' \ "$@" Actual result: -------------- Backtrace (created running the snapshot, without debug): (gdb) bt #0 0xb6e63777 in zval_mark_grey (pz=0x9fd0cf8) at /root/php5.3-200912040930/Zend/zend_gc.c:360 #1 0xb6e63d35 in gc_collect_cycles () at /root/php5.3-200912040930/Zend/zend_gc.c:417 #2 0xb6e48285 in zend_deactivate () at /root/php5.3-200912040930/Zend/zend.c:900 #3 0xb6df767f in php_request_shutdown (dummy=0x0) at /root/php5.3-200912040930/main/main.c:1606 #4 0xb6ec8aa9 in php_handler (r=0x9bc31d0) at /root/php5.3-200912040930/sapi/apache2handler/sapi_apache2.c:493 #5 0x0807a1c9 in ap_run_handler () #6 0x0807d5e1 in ap_invoke_handler () #7 0x0808af00 in ap_internal_redirect () #8 0xb73356c3 in ??
