Every time I execute the same program, its stack starts at a different
address. After some studying, I know it is caused by stack randomization
in kernel. Although stack randomization impedes stack buffer overflow,
it introduces some nondeterminism.
Does anyone know how to disable it?
Thank you in advance.

I'm afraid I can't help, but I'm curious: what are the behaviors that
the randomization is causing? Not criticizing, just interested.

I got the way:
sysctl -w kernel.randomize_va_space=0
Disabling stack randomization is usefull for learning.
