Did you mean "set disable-randomization" off in the above example?
Plus, are you saying that enabling randomization *** in a separate ***
gdb session then enabled randomization for all subsequent gdb sessions?
If so, that's a kernel bug.
I still can't reproduce the problem.
Let's first pin down your repro.
Can you paste an unedited session log, starting from the shell command that
launches gdb?
And, on the off chance (seems unlikely, but who knows), what's your kernel
version?
