the conf file:

<database %[\\/]employee.fdb>
enabled true
include_filter %(SELECT|INSERT|UPDATE|DELETE)%
log_statement_prepare true
log_statement_free true
log_statement_start true
log_statement_finish true
log_connections true
log_transactions true
</database>

in UIB

with TUIBQuery.Create(UIBTransaction1) do
try
SQL.Text := 'SELECT * FROM COUNTRY;';
Open(False);
// ...
Close(etmStayIn); // FreeStatement(DSQL_unprepare)

SQL\.Text := 'SELECT \* FROM CUSTOMER;';
// it crashes while repreparing the statement using the same statement handle
Open\(False\); // Prepare\(unprepared statement handle\)
// \.\.\.
Close\(etmCommit\);

finally
Free;
end;
