RE: Macos notarization and "Unkown signal" on macos

Sorry for not responding earlier, but I was out sick the last weeks.

I intentionally copied some lines to make it easier to find the relevant part in the LLDB source code, just in case anyone else wants to dig deeper. Macos documentation on this is unfortunately rather sparse, so every bit helps IMO.
I know that this would cause legal issues, which is why I only posted my findings here and not in the patches mailing list. My intention was to start a discussion on how to solve the problem, not to get this patch accepted. I am confident that we can come up with a patch that doesn't infringe any copyright. 90% of the patch are "normal" system calls anyway.

Bother: could "inspired by LLDB" mean that the code was copied from
there?  This could mean legal problems if we accept such code.

IOW, how much of the code is actually your own original code?
