Assuming the debugger setup is correc
Thank you for the link, I have changed some options, but the assembler window still pops up.
Are you working with some third party components with reference to external dlls?
No, I'm writing my own code. I use Debian Stable, my copy of Lazarus is from its repository.
Here is an example of code that gets these pop-ups:
program project1;
begin
write('Hello!');
write('Goodbye!');
end.
