ODBC - Getting CONN ERROR: errmsg='The buffer was too small for the InfoValue'

I've ported a powerbuilder application to postgresql. Tested ok on
windows 10 64, was installed on two win10-64 other computers, all
connecting the postgresql database in the localhost with access via odbc.
The third of them presented the error detailed below in the logs (mylog and
psqlodbc) integrally copy and paste.

- The application send the connect command and receive error "IM001"as a
response.
- The ODBC interface test shows "connection successful".
- The log tell us that the connection to the database was effectively
completed by the driver.
- All versions of the odbc driver and database are reported in the logs.
- The connection string and the used parameters etc are fully documented in
the logs.
- I've tried many basic stuff like upgrade/downgrade versions of the driver
and database without success.
- The powerbuilder version is an old 32 bit 6.5

Can anyone help me?
