Neither of the reasons look important enough, compared to the http://www.akkadia.org/drepper/no_static_linking.html Especially as libasan is overriding malloc etc., having dozens of malloc overrides in different shared libraries, perhaps all chaining into each other, is a nightmare. For 2), libasan should just use symbol versioning and provide backwards compatibility as long as it is possible, or worst case bump SONAME occassionally. Jakub
