Operating system:   Windows XP
Description:        ODBC driver v8.4.1 crashed
Details:

Hello,
in my application the PostgreSQL ODBC driver v8.4.1 sometimes crashed when
accessing a PostgreSQL v8.3.6 server.
I want to read out data from a column of type "TEXT". I use a simple SQL
query "SELECT prg FROM testdata WHERE id=1234".
Inside the following C call

rcode = ::SQLGetData(m_hStmt, nCol, SQL_C_CHAR, m_szString, nBufSize,
&sdODataLength);

the psqlodbc35w.dll crashes (probably depending on the column data).
I've got Mini Dumps of these crashes. Just tell me if you need them.

Do you already know something about this problem?
Best regards,
Gerhard
