- hoyhoy 8mo agoASAN/LSAN is amazing. It absolutely monkey-hammers performance though.

- vlovich123 8mo agoBecause it can only catch a subset of issues, it’s not guaranteed to catch issues (probabilistic), even issues it “could” catch may not be caught due to temporal distance of the free and a subsequent use, and requires the use of a different allocator that supports it. It’s also unclear to me how it know whether a given free is for a sampled or unsampled region - I suspect it must capture all free/realloc to accomplish that but it does imply all of these are sampled. It’s nowhere near the same as robust bounds checking.
