I see you suffer from RAS syndrome :)

In all seriousness though, is there anywhere explaining what the issue with GDB
is? I see [1] but that is from a while ago and talking about PIEs themselves
not working. It's not completely out of the question that I will look into it
(though no promises, I have a lot of things I want to get done...).

Ideally, yes. In practice, it works but gdb is lost with PIE
executables, so that has to be fixed first.
