There was a problem hiding this comment.
Should we remove md5?
From my experience interceptors, other then alloc, mem* str*, detect very few issues, however require some maintaince.
Some interceptors are unavoidable to maintan state, e.g. signals, pthread etc. For msan almost all interceptors are needed. However for asan they are mostly optional.
So looking back, in my opinion, we should rather avoid interceptor if we can.
