You are wrong. Both integer overflow sanitizers and those various 
modern memory/address sanitizers are not meant to be used in the 
final release of the code. They are meant to be used one at a 
time during testing or debugging (and the memory sanitizers slow 
down the code 2-3 times, so they can be used in many cases of 
debugging), and then later disabled.
