[mORMot] Database connection error with ZEOS

[mangakissa]

My real goal is to connect a databaseserver and get data remotely.
My own first example is working (both Delphi/Lazarus). I created a SQLite database and put some data in it.

My own second example connects to a database server (MariaDB 5.5). I looked in the manual and took the code from chapter 8.1  (Lazarus 1.6Rc1/ FPC 3.0):

Code: Pascal  [Select][+][-]

1. unit Unit1;
2.  
3. {$mode objfpc}{$H+}
4.  
5. interface
6.  
7. uses
8.   Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls,
9.   SynCommons,  mORMot, mORMotSQLite3, SynSQLite3Static,
10.   mORMotDB,  synDB,  
11.   SynDBZeos, // needed for Zeos
12.   ZDbcMySql; // needed for Zeos
13.  
14. type
15.  
16.   { TForm1 }
17.  
18.   TForm1 = class(TForm)
19.     Button1: TButton;
20.     Memo1: TMemo;
21.     procedure Button1Click(Sender: TObject);
22.   private
23.     procedure UseProps(Props: TSQLDBConnectionProperties);
24.     { private declarations }
25.   public
26.     { public declarations }
27.   end;
28.  
29. var
30.   Form1: TForm1;
31.  
32. implementation
33.  
34. {$R *.lfm}
35.  
36. { TForm1 }
37.  
38. procedure TForm1.Button1Click(Sender: TObject);
39. var Props: TSQLDBConnectionProperties;
40.     Server : string;
41. begin
42.   Server := 'zdbc:mysql://192.168.x.x:3306/test?username=xxx;password=xxx';
43.   Props := TSQLDBZEOSConnectionProperties.Create(Server,'test','','');
44.   try
45.     UseProps(Props);
46.   finally
47.     Props.Free;
48.   end;
49. end;
50.  
51. procedure TForm1.UseProps(Props: TSQLDBConnectionProperties);
52. var I: ISQLDBRows;
53. begin
54.   I := Props.Execute('select * from gebruikers where id = ?',['1']);
55.   showmessage(I.Column['login']);
56. end;
57.  
58. end.
59.  
60.  

Examples compiles without problem, but when I want to get data from the database, I get this error:

    Project voorbeeld2 raised exception class 'External: SIGSEGV'.

    In file 'C:\lazarus16RC1\components\zeoslib714\src\plain\ZPlainMySqlDriver.pas' at line 1240:
    Result := PMYSQL_ROW(ROW)[Offset];

It looks the database will not be connected. Is my code wrong or do I have to do something else?
