PHP Bug Type: ODBC related
Bug description: odbc_connect segmentation fault
Description:
------------
As reported in Bug 34716, but I have a backtrace for you.
Using
Apache/2.0.46
PHP/5.1.0RC5-dev (snapshot php5-200511071930)
unixODBC-2.2.11
php compiled with
./configure --with-apxs2=/usr/sbin/apxs --with-mysql=shared
--with-unixODBC=shared --enable-debug
When accessing the script via brower or command line, results in a
segfault.
`isql Customer -v` results as expected and able to execute queries.
Reproduce code:
---------------
<?php
//database connection
$conn=odbc_connect('CUSTOMER','tsi','');
if (!$conn)
{exit("Connection Failed: " . $conn);}
//output
echo "Test";
?>
Expected result:
----------------
I expect it to simply connect, print Test, then disconnect.
Actual result:
--------------
Segmentation fault with no output.
