Hi All,
In my Lazarus application I use a TPanel descendant component (TMyPanel)
which have subpanels (TMySubPanel) which are TPanel descendants also.
The subpanels accessed through a TList. If add a new subpanel into the
main panel added to the list with TList.Add if remove a subpanel from it
remove from the list with TList.Remove then call TMySubPanel.Free. My
main development platform is x86_64-Linux and the application works like
a charm. But with the Windows version of the app (cross compiled to
i386-Win32) got an "Access violation." at TMySubPanel.Free. If start
with gdb got "Program received signal SIGSEGV, Segmentation fault.
0x004041c4 in fpc_check_object ()" at TMySubPanel.Free.
I completely don't understand what is the source of the problem and why
the two platforms behaves differently.
Cannot have a simple test case just a dumb example.
procedure TForm1.FormCreate(Sender: TObject);
var
x:TPanel;
begin
x.Free;
end;
With Linux no error (x is Nil before the Free call), with Windows got
SIGSEGV (x is not Nil before the Free call). Is it a Lazarus thing or
come from FPC?
