Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows (zip):
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

For Windows (installer):

  http://snaps.php.net/win32/php5.2-win32-installer-latest.msi

And I also suggest using the PDO ODBC driver instead..

Description:
------------
The odbc_result() function crashes if the value requested is a NULL
value in the DB.

Tested on: RHEL 4 WS   64 bit
Architecture: x86_64
PHP version: 4.3.9
DB: PostgreSQL 8.2.4
unixODBC: 2.2.9 


$field_value = odbc_result($this->Query_ID, $i );

where $i is an index of a NULL value in the DB.

Reproduce code:
---------------
$field_value = odbc_result($this->Query_ID, $i );

where $i is an index of a NULL value in the DB.

Expected result:
----------------
$field_value == "" or "NULL" or ERROR, but I do not expect a crash :)

Actual result:
--------------
Simply a crash!
