Summary0037885: Debugger hangs if program previously aborted with error
DescriptionThis is kinda a follow up of 0037861, though I have not checked whether it behaved this way before the addition of the dialog as well (though it does not happen with 2.0.10).

I have the following main program:

program tdlltest;

{$mode objfpc}{$H+}

procedure Test; external 'Foobar.dll' name 'Test';


The library Foobar.dll does not exist, so running it will abort with an error.

Now for the following it doesn't matter if I have the "dialog on error" enabled or not: if I run the program again the IDE will change its title bar to "(Debugging...)", but the stop button won't be enabled and no command line window will appear. The debug output window is empty. Trying to close the IDE will display the "do you want to stop debugging"-dialog and no matter what the IDE won't terminate after the dialog is confirmed. I need to kill it using Task Manager.
Additional InformationThis happens with both versions of GDB provided by Lazarus.

It does not happen if the program ran without error.
TagsNo tags attached.

Will be looking into it....

The "no matter what" => try: Run > Reset debugger. That should at least get it stopped.

Okay, yes, had totally forgotten about "Reset debugger". That works. :)

Please test and close if ok.

After the first launch failed, the debugger would not even attempt to run the exe again.
