[PATCH] D135713: [cmake][Fuchsia] Add -ftrivial-auto-var-init=zero to runtimes build

[Roland McGrath via Phabricator via cfe-commits]

mcgrathr added a comment.

I had imagined making lsan always do this since there's a specific lsan-related rationale for it that applies to everybody.
I'm not clear on how cmake structures things and whether sanitizer_common would have to do it unconditionally since it's used by lsan code.

Doing this generally seems fine to me, but in the general case it's considered a bug-masking feature (with =zero) and we should contemplate how much we want to expect that compiler-rt might have bugs that we will be making it harder for us to notice and properly fix.
