mpx is new to me, but looking at the docs it solves a different
problem than asan

asan must not be used in production code, it's not a hardening
solution, but a debugging one (it actually increases the attack
surface by all its instrumentations, its own set of reliance on
ub and strong interdependency on libc internals)

mpx is for hardening deployed code with bounds check instructions
