Navid Madani 1 Posted February 11 I have encountered a strange problem: Delphi Athens is running via Parallels on Apple Silicone. In the following demo, none of the destroyers are called when targeting macOS ARM 64, while everything works OK targeting Windows). Also, I can get the Windows target to report the memory leak when I comment out fDebug.Free in FormDestroy, but not with macOS ARM 64. Can anyone else reproduce this? Am I missing something? Thanks! unit Unit1; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs; type TForm1 = class(TForm) procedure FormDestroy(Sender: TObject); procedure FormCreate(Sender: TObject); private fDebug: TObject; public destructor Destroy; override; end; var Form1: TForm1; implementation {$R *.fmx} // TForm1.FormDestroy is not called when Target is macOS ARM 64-bit procedure TForm1.FormDestroy(Sender: TObject); begin ShowMessage('FormDestroy Called'); fDebug.Free; end; // TForm1.Destroy is not called when Target is macOS ARM 64-bit destructor TForm1.Destroy; begin ShowMessage('Destroy Called'); inherited; end; procedure TForm1.FormCreate(Sender: TObject); begin fDebug := TObject.Create; end; end.

Patrick PREMARTIN 65 Posted February 11 It's not new : destroy of the main form and finalization bloc in units is not executed on Mac since years. On Mac, for the main form use the onClose event instead of onDestroy. Share this post Link to post

LGROX 0 Posted February 12 I also stumbled upon this bug in one of my multi device apps when I tried to save data to a file within an OnDestroy event in a data module. Nothing was saved! The same problem in both macOS for Intel and macOS for ARM. In reality, it’s even more serious. Neither OnDestroy nor destructors in forms or data modules are called when Mac apps are shut down! As a workaround, as mentioned earlier, you can place shutdown code in the main forms’ OnClose events. However, OnClose doesn’t exist in data modules, so in this case, the shutdown code must be called from the main form. The problem is reported in RSP-26436, but only that the main form’s OnDestroy is not called. However, the issue is indeed worse. Unfortunately, QualityPortal is currently closed for new comments, but voting is still possible, so please vote to address this critical bug! 🙏 Share this post Link to post
