See: http://cvs.php.net/viewvc.cgi/php-src/ext/sybase_ct/tests/bug43578.phpt?revision=1.1.2.1&view=markup&pathrev=PHP_5_3 ------------------------------------------------------------------------ [2007-12-12 10:28:24] schulmat at cms dot hu-berlin dot de Description: ------------ The problem can reproduced on Solaris 9 and Solaris 10. If I compile php with ./configure \ --prefix=/usr/local/wwwbin/php-5.2.5 \ --with-apxs2=/usr/local/wwwbin/apache/bin/apxs \ (Apache 2.2.6) --with-sybase-ct=/opt/csw (freetds-version 0.64 from blastwave) and perform this simple query: select DC_Rights from Resource R where R.Resource_ID = 123; (DC_Rights type text, Resource_ID = 123 exists, should return "(empty) not NULL, works via tsql) i get "Incurred fault #6". Reproduce code: --------------- <?php require("DBConnection.cls.php"); // database connection $db=new DBConnection(); // new object $test = "set textsize 262144"; echo $test."<br />"; //$db->submitQuery($test); flush(); $query = "select DC_Rights from Resource R where R.Resource_ID = 122"; // expected Result: NULL flush(); $res_id = $db->submitQuery($query); // works! $query = "select DC_Rights from Resource R where R.Resource_ID = 123"; // expected Result: "" flush(); $res_id = $db->submitQuery($query); // doesn't work. Apache: Segmentation fault (11) echo "done!"; flush(); exit(); ?> Expected result: ---------------- set textsize 262144 select DC_Rights from Resource R where R.Resource_ID = 122 select DC_Rights from Resource R where R.Resource_ID = 123 done! Actual result: -------------- Output: Warning: sybase_connect() [function.sybase-connect]: Sybase: Server message: Changed client character set setting to 'iso_1'.
