I have an win32 multithreaded program written in lazarus 1.7, FPC 3.1.1
From time to time, when it quits, it will freezes and from the task manager, the program will occupies the entire CPU core.
I noticed that it will happen more often if:
1)
constructor TMyComponent.Create(TheOwner : TComponent);
begin
self.some_component := TSomeComponent.Create(TheOwner);
end;instead of
constructor TMyComponent.Create(TheOwner : TComponent);
begin
self.some_component := TSomeComponent.Create(self);
end;2) if the program executes some methods of a nil object
3) if I don't do a build all when some common units are changed by another project.
Since this freezing behaviour does not happen during debugging, I have spent months trying to fix it but failed.
Any suggestions are welcome.
