From: dmitry dot dulepov at gmail dot com Operating system: SuSE Linux 10.3 PHP version: 5.2.5 PHP Bug Type: Reproducible crash Bug description: Apache crash because PHP frees memory twice
Description: ------------ >From time to time Apache crashes inside PHP. It is impossible to reproduce by executing a single script but this happens several times a week. I cannot get a backtrace because this is no single script that crashes. It just crashes from time to time. I use official distributions from SuSE 10.3. Actual result: -------------- Stack trace: *** glibc detected *** /usr/sbin/httpd2-prefork: munmap_chunk(): invalid pointer: 0x00007fff56096260 *** *** glibc detected *** /usr/sbin/httpd2-prefork: double free or corruption (out): 0x00007fff56094780 *** ======= Backtrace: ========= /lib64/libc.so.6[0x2b6e5675a21d] /usr/lib64/apache2/mod_php5.so(zend_shutdown+0x7b)[0x2b6e5a1e623b] /usr/lib64/apache2/mod_php5.so(php_module_shutdown+0x2a)[0x2b6e5a1a228a] /usr/lib64/apache2/mod_php5.so(php_module_shutdown_wrapper+0x9)[0x2b6e5a1a2329] /usr/lib64/apache2/mod_php5.so[0x2b6e5a265471] /usr/lib64/libapr-1.so.0[0x2b6e55c7686d] /usr/lib64/libapr-1.so.0(apr_pool_destroy+0x2d)[0x2b6e55c76e9d] /usr/sbin/httpd2-prefork[0x5555555a14ce] /usr/sbin/httpd2-prefork[0x5555555a14fb] /lib64/libpthread.so.0[0x2b6e562d9fb0] /usr/lib64/apache2/mod_php5.so(php_strlcpy+0x15)[0x2b6e5a1ae3c5] /usr/lib64/apache2/mod_php5.so(php_realpath+0x3f4)[0x2b6e5a1a0884] /usr/lib64/apache2/mod_php5.so(virtual_file_ex+0x1d5)[0x2b6e5a1a0b75] /usr/lib64/apache2/mod_php5.so(expand_filepath+0x10d)[0x2b6e5a1a870d] /usr/lib64/apache2/mod_php5.so(_php_stream_fopen+0x4d)[0x2b6e5a1bbaad] /usr/lib64/apache2/mod_php5.so(_php_stream_fopen_with_path+0x91)[0x2b6e5a1bc451] /usr/lib64/apache2/mod_php5.so(_php_stream_open_wrapper_ex+0xdd)[0x2b6e5a1b74ed] /usr/lib64/apache2/mod_php5.so(php_stream_open_for_zend_ex+0x1f)[0x2b6e5a1a300f] /usr/lib64/apache2/mod_php5.so(zend_stream_fixup+0x2c)[0x2b6e5a1fa1ec] /usr/lib64/apache2/mod_php5.so(open_file_for_scanning+0x1b)[0x2b6e5a1c597b] /usr/lib64/apache2/mod_php5.so(compile_file+0x8d)[0x2b6e5a1c5ced] /lib64/libgcc_s.so.1[0x2b6e5af9d8fc] [0x555555816240] -- Edit bug report at http://bugs.php.net/?id=44309&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44309&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44309&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44309&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44309&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44309&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44309&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44309&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44309&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44309&r=support Expected behavior: http://bugs.php.net/fix.php?id=44309&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44309&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44309&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44309&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44309&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44309&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44309&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44309&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44309&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44309&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44309&r=mysqlcfg
