Bug #64611 [NEW]: Segfault using ODBC with SQL Server "Native Client"
From: brandonkirsch at gmail dot com
Operating system: Linux - OpenSuse 12.2 64-bit
PHP version: 5.5.0beta1
Package: ODBC related
Bug Type: Bug
Bug description:Segfault using ODBC with SQL Server "Native Client"
Description:
------------
A segfault has existed in PHP since at least 5.2.17 when using ODBC with
SQL Server Native Client driver.
Selecting NULL values in a computed expression causes the segfault.
I created a patch for this over a year ago and submitted the pull request
here: https://github.com/php/php-src/pull/193
The pull request has not been accepted, so the segfault still exists even
in 5.5.0beta2.
Test script:
---------------
<?php
$conn = odbc_connect('Driver=SQL Server Native Client
11.0;server=xxx;uid=xxx;pwd=xxx;Database=xxx','','');
$query = odbc_exec($conn, 'select null');
$segfault = odbc_fetch_array($query); // segfault
Expected result:
----------------
odbc_fetch_array to return a result rather than segfault.
Actual result:
--------------
segfault.
