See <http://bugs.php.net/bug.php?id=10643>, <http://bugs.php.net/bug.php?id=8298> and <http://www.php.net/manual/en/ref.oci8.php> (the last one seems to imply that it's not only a bug in glibc-2.1.3, but also happens elsewhere). ------------------------------------------------------------------------ [2002-11-27 17:22:17] iliaa@php.net Apache 1 & PHP do not need to be linked against a threading library. Apache 1 operates on a pre-fork model, meaning that it forks child processes rather then making threads. ------------------------------------------------------------------------ [2002-11-27 17:05:03] michael dot mauch at gmx dot de Try configuring your Apache with the pthread library: LDFLAGS="-lpthread" ./configure ... (or if your platform doesn't have a pthread library: use "ldd libphp4.so" and "ldd httpd" and make sure that both of them are linked to the same thread library). ------------------------------------------------------------------------ [2002-11-27 16:45:15] iliaa@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. The crash appears to occur deep inside the Apache code (last 9 steps). You may get more meaningful data if you compile Apache with debug symbols, but given the provided backtrace the crash does not appear to be the fault of PHP. ------------------------------------------------------------------------ [2002-11-27 10:33:29] henka at isp dot org dot za Sample script: <?php print "hello world!"; ?> apache-1.3.27 configured with: ./configure --enable-module=unique_id --enable-module=rewrite --enable-module=usertrack --enable-module=so PHP-4.2.3 configured with: ./configure --with-pgsql --with-interbase --with-mysql=/usr/local/mysql/ --with-apxs=/www/bin/apxs --with-openssl --enable-debug gdb backtrace: Program received signal SIGSEGV, Segmentation fault. 0x4020f466 in ??
