[PATCH] D79133: [scudo] Zero- and pattern-initialization of memory.

[Alexander Potapenko via Phabricator via llvm-commits]

glider added a comment.

Out of curiosity, is there any reason to have pattern initialization for heap?
As security researchers note (see the discussion of stack initialization on cfe-dev), zero-initialization has a smaller probability of making existing bugs exploitable.
On the other hand, there is no downside in making the heap zero-initialized, as library features do not introduce language dialects.
