PHP 4.0 Bug #9079: PHP seg faults in alloca() at first PHP request to Apache

From: mchampagne@capis.com Operating system: AIX 4.3.3 PHP version: 4.0.4pl1 PHP Bug Type: Scripting Engine problem Bug description: PHP seg faults in alloca() at first PHP request to Apache We are running Oracle IAS 1.0.0.0 on AIX 4.3.3. Oracle's IAS runs Apache 1.3.9 and the root Apache directory is in /ias/Apache/Apache. We have a soft link from /usr/local/apache -> /ias/Apache. We are installing our PHP source from /usr/tools/src/php-4.0.4pl1/ and I believe the config script uses /usr/local as it's prefix? We ran make and make install and we bring up Apache with mod_php successfully. At the first request however, php cores in the /ias/Apache/Apache directory. The request is simply running phpinfo(). I see the following message in our httpds_error_log: [Fri Feb 2 11:26:34 2001] [notice] Apache/1.3.9 (Unix) PHP/4.0.4pl1 mod_perl/1.21 ApacheJServ/1.1 configured -- resuming normal operations [Fri Feb 2 11:26:58 2001] [notice] child pid 17026 exit signal Segmentation fault (11) Here's what I see in the core file: Segmentation fault in sig_coredump at 0x10003824 0x10003824 (sig_coredump+0x3c) 80410014 l r2,0x14(r1) (dbx) where sig_coredump(0xb) at 0x10003824 alloca() at 0xd36ccef8 php_execute_script(0x2ff22530), line 1181 in "main.c" apache_php_module_main(0x20255e30, 0x0), line 89 in "sapi_apache.c" send_php(0x20255e30, 0x0, 0x20257dc0), line 516 in "mod_php4.c" send_parsed_php(0x20255e30), line 527 in "mod_php4.c" ap_invoke_handler(0x20255e30) at 0x100c3138 process_request_internal(0x20255e30) at 0x100edf8c ap_process_request(0x20255e30) at 0x100ef4f8 child_main(0x0) at 0x10002058 make_child(0x2004ed20, 0x0, 0x3a7adfba) at 0x10001a18 startup_children(0x5) at 0x10001804 standalone_main(0x3, 0x2ff229e8) at 0x10000d24 http_main.main(0x3, 0x2ff229e8) at 0x100008c8 Our configure scripts is run with: configure --with-apxs=/ias/Apache/Apache/bin/apxs --with-oci8=/ias/6iserver --without-mysql We also made the modification to libtool in bug 4360 and tried again but we get the same as above. -- Edit Bug report at: http://bugs.php.net/?id=9079&edit=1
