Hi,
I'm sorry for a long delay, I've been very, very busy lately.
Hopefully I'd have more time for GDB now...

Neither I know. I'm using Debian Buster which seems to have -no-pie
by default too.

No, I don't know how universal -no-pie is. From what I have understood
from Simon (https://sourceware.org/ml/gdb-patches/2018-08/msg00662.html),
out of the options available -no-pie is still the best bet.
