ASAN vs. Valgrind Experience


Recommended Posts

Curious if anyone has gotten valgrind to work with 0AD builds. Asking because some of the development documentation references valgrind (https://trac.wildfiregames.com/wiki/CodeQuality#Valgrind) which takes something on the order of a 10-20x hit in runtime performance while ASAN is closer to 2-4x perf hit (https://developers.redhat.com/blog/2021/05/05/memory-error-checking-in-c-and-c-comparing-sanitizers-and-valgrind#performance). At that point, running replays or even full games under ASAN may be reasonable compared to Valgrind which isn't feasible.

Some people have done for a while you need to pass an extra flag when updating workspaces.sh to make use of it
