Summary: User applications may register hooks in the .CRT$XL* callback list, which is called very early by the loader. This is very common in Chromium: https://cs.chromium.org/search/?q=CRT.XL&sq=package:chromium&type=cs This has flown under the radar for a long time because the loader appears to catch exceptions originating from these callbacks. It's a real problem when you're debugging an asan application, though, since it makes the program crash early. The solution is to add our own callback to this list, and sort it very early in the list like we do elsewhere. Also add a test with such an instrumented callback, and test that it gets called with asan.
