ZEOSLIB: External SIGSEGV when set properties in runtime!

[lrmirabelli]

Hello folks! How are you?

I'm with a "simple fool trouble" with ZeosLib and Lazarus, in a new project.
I want to configure the ZConnection parameters in runtime, because I will get these parameters from a "ini" file.

I'm using:

• Windows 10 Home x64

• ZeosLib 7.2.8

• Lazarus 2.0.10 x64

• FPC 3.2.0

• SVN 63526

So, I created a new application, just with Main Form and a DataModule.
In these DataModule, I added a ZConnection and save it as "dbConn" name, and the class as "u_dbmod.pas". I want put here all data components.

And, in the MainForm, I declared the "u_dbmod" in the Implementation section, added one button wich calls the procedure "TDataModule1.CfgParams()" as follow:

Code: Select all

procedure TDataModule1.CfgParams();
begin
     dbConn.HostName := '';
     dbConn.Port := 5555;
     dbConn.UserName := 'posgtres';
     dbConn.Password := 'masterpass';
end;

In design time, I can configure all parameters of ZConnection, and I can to connect with success to my Database.
BUT..... in runtime, when I click in the button to set these configuration by instructions, the Lazarus shows the follow error message:

Error: Project raised exception class 'External:SIGSEGV'.
In file 'u_dm.pas' in line 33:
dbConn.HostName := '';

Can anyone help me to understand why I can't to do this procedure at runtime?
Where's the error in that logic?

Since now I thank all for attention.

Thank you!!!

Best regards;
LRM
