EXCEPTION_ACCESS_VIOLATION Error: 17310, Severity: 20, State: 1.

I am using the latest IBM INFORMIX ODBC DRIVER 3.00.00.13223 - ICLIT09B.DLL I
then use a link server – Microsoft OLE Database Provider for ODBC Driver. Both ODBC
and Linked server test connection successfully and I can return most records
in a table from Informix; however, some tables have a text and char columns
that produce the error:

Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should
be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should
be discarded.



Here's my SQL and ERRORS

USE [TASA]
GO
SET NOCOUNT ON

SELECT
[descrip]
FROM
[tasa1_ptrack].ptrack.tasa.equip

NOTE: If I select any other column in that table it returns no problem.

Results in SQL error:

Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should
be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should
be discarded.
