It finds use-after-free and out-of-bounds errors with very little overhead. Could be useful.

On OS X, you can use libgmalloc. It isn't that slow.

I agree this looks really cool. Needs compiler support.

subset of valgrind, doesn't improve accuracy, de-milestoning

[graydon]

just a bug, removing milestone/nomination.

Ah, this is clever. They beat valgrind because they add instrumentation into the code while it's being compiled, rather than preloading stuff at runtime. For our purposes this is fine; since we have a dedicated set of valgrind bots, they can just do make ASAN=1 or whatever from the start.

(Triage visit in disguise.)

By the way, the paper is clearly-written and pretty approachable.

To compile with asan:

rustc --passes asan,asan-module --link-args "/usr/bin/../lib/clang/3.4/lib/linux/libclang_rt.asan-x86_64.a" foo.rs
