I found the culprit. In TIBConnection.PrepareStatement's variable section, x was declared as a shortint which would cause problem when its used for allocating memmory for the SQLVAR elements, when there are more than 128 fields. Also same as above in TIBConnection.FreeSQLDABuffer. I changed var x in both location into smallint and everything worked fine for me. I'm not sure weather it will impact any parts of TIBConnection, so I will leave it to the fcl-db governors to decide.
