#20193 [NEW]: zend_get_parameters_ex segfault PHP on script end

From: drxor@intellaxiom.com Operating system: Linux 2.4.12 PHP version: 4.2.3 PHP Bug Type: Zend Engine 2 problem Bug description: zend_get_parameters_ex segfault PHP on script end I have an extension which is working well in PHP 4.2.2 but when I compile it with PHP 4.2.3. The scripting engin crash on the end of the script several times. I comment out the zend_get_parameters_ex and put static parameters and the script work well. There is the function in my extension (every function using parameter may crash PHP) PHP_FUNCTION(ia_open) { zval **spHost_arg, **spPort_arg; char *spHost = NULL; char *spPort = NULL; TIA_Stream* olStream; TIA_Stream* olResStream; TIA_Writer* olWriter; TIA_Reader* olReader; int sockfd; int nlRes=-1; //If I use this it may crash PHP #if 0 if (ZEND_NUM_ARGS() != 2 || /*this part may crash PHP*/zend_get_parameters_ex(2, &spHost_arg, &spPort_arg) == FAILURE){ WRONG_PARAM_COUNT; } convert_to_string_ex(spHost_arg); spHost = Z_STRVAL_PP(spHost_arg); convert_to_string_ex(spPort_arg); spPort = Z_STRVAL_PP(spPort_arg); #else //It's ok with this code spHost = "xxxxx"; spPort = "1111"; #endif sockfd = connecttounix(); olStream = new TIA_Stream(); olWriter = new TIA_Writer(olStream); olWriter->WriteInteger (knIA_Open); olWriter->WriteString (spHost); olWriter->WriteString (spPort); delete olWriter; olResStream = new TIA_Stream(); if ( request(sockfd, olStream, olResStream) == 0) { olReader = new TIA_Reader(olResStream); nlRes = olReader->ReadInteger(); delete olReader; } delete olResStream; delete olStream; disconnectfromunix(sockfd); RETURN_LONG (nlRes); } There is some output of PHPINFO System Linux orion 2.4.12 #1 Wed Oct 24 03:59:50 EDT 2001 i686 unknown Build Date Oct 28 2002 09:54:34 Configure Command './configure' '--with-mysql=/usr' '--with-apxs' '--with-interbase=/opt/interbase' '--with-gettext' '--with-xml' '--with-gd' '--with-png-dir=/usr' '--with-zlib-dir=/usr' '--with-imap=../imap-2002.RC8' '--with-imap-ssl=../imap-2002.RC8' Server API Apache Virtual Directory Support disabled Configuration File (php.ini) Path /usr/local/lib/php.ini Debug Build no Thread Safety disabled -- Edit bug report at http://bugs.php.net/?id=20193&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=20193&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=20193&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=20193&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=20193&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=20193&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=20193&r=support Expected behavior: http://bugs.php.net/fix.php?id=20193&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=20193&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=20193&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=20193&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=20193&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=20193&r=dst IIS Stability: http://bugs.php.net/fix.php?id=20193&r=isapi
