(gdb) :o) ------------------------------------------------------------------------ [2004-08-19 18:27:58] hip at cs dot okstate dot edu I getting a seg. fault on a simple little script that's worked for years and it sure smells like stack corruption. <? require_once("config.inc"); require_once("Database.inc"); $db = new Database(USER_ID, USER_PASSWORD); $db->connect(); $sql = "select from STUDENT_STATUS "; $sql .= "where STATUS='APPROVED' "; ?> On my solaris 9 x86 box this seq. faults. Change the last line it seq faults. Remove the last line it doesn't. After a hour of playing, I've discovered that I can prevent a seg. fault by place echo statements (or some other random statment) in key positions in the file. That sure smells like stack corruption. I ran gdb on the core dump and the last lines of the backtrace are: #20 0x81b65da in zend_deactivate () at /usr/local/src/php-5.0.1/Zend/zend.c:819 #21 0x8182007 in php_request_shutdown (dummy=0x0) at /usr/local/src/php-5.0.1/main/main.c:1212 #22 0x81db50f in main (argc=2, argv=0x8047a18) at /usr/local/src/php-5.0.1/sapi/cli/php_cli.c:1046 and from what little I know of gdb it looks like it's happening when php is trying to shutdown. ------------------------------------------------------------------------ [2004-08-18 20:36:46] sparkeh at btinternet dot com N.B. Original code tested and works as expected with PHP 4.3.3 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
