PHP Bug Type: ODBC related
Bug description: httpd segfaults when odbc_pconnect called with incorrect
username/password
Description:
------------
When attempting to connect to an odbc data source via odbc_pconnect with
incorrect username and/or password, the httpd (apache) instance handling
that connection segfaults.
OS is Centos 5 (RHEL5) running in a vmware server virtual machine 32 bit
I am using ODBC to connect to a mysql server running on localhost for
persistent db connections and mysql stored proc support.
Reproduce code:
---------------
<HTML><BODY>
<?php
$link_id = odbc_pconnect('Default', 'root','badpassword');
if(!$link_id){die("no connection!");}
else{echo "connected";}
?>
</BODY></HTML>
Expected result:
----------------
user should see connected printed on web page.
Actual result:
--------------
