Bug description:NULL valued anonymous column causes segfault in odbc_fetch_array
Description:
------------
odbc_fetch_array segfaults when the result consists of one-column anonymous
NULL-valued tuple
our environment:
OS: windows server 2003 R2, apache 2.2 + mod_fcgid + PHP5.3.10
(reproducible with 5.3.6)
DB: SQL Server 2005
odbc driver: SQL Server Native Client 10.0
tried also with postgres, it seems to me that postgres amends the result
with generated name of that column ('sum' in this case)
Test script:
---------------
$conn = odbc_connect(
"Driver={SQL Server Native Client 10.0};Server=<some microsoft sql
server>;Database=<any db name>;Trusted_Connection=yes"
, ''
, ''
);
$res = odbc_exec(
$conn
, 'SELECT SUM(1)
FROM information_schema.tables
WHERE 3 = 2'
);
$row = odbc_fetch_array($res);
odbc_free_result($res);
odbc_close($conn);
var_dump($row);
Expected result:
----------------
array(1) {[0]=> NULL}
or E_WARNING
Actual result:
--------------
segfault, apache log says:
[warn] [client x.x.x.x] (OS 109)The pipe has been ended. : mod_fcgid: get
overlap result error
[error] [client x.x.x.x] Premature end of script headers: foo.php
[info] mod_fcgid: process
C:/Webserver/Apache2.2/php-5.3.10/php-cgi.exe(4420) exit(communication
error), return code -1073741819
eventlog says:

PHP itself does not produce any sort of output
