In STL-ASan-CI runs, seemingly random x86 test cases fail with exit code 3221225477 (0xC0000005) indicating an Access Violation. Let's track sporadic AVs here and see if there's a pattern.

Note that these invalid accesses are not caught and reported by the ASan runtime, so they are presumably uninstrumented. Together with the fact that this is ASan-only and x86-only, I suspect a race in ASan setup or teardown.

This is on no way an exhaustive list: we've missed tracking some, and nearly given up after 2024-08 because they are so frequent. In any case, there seems to be no pattern. It's probably some kind of shutdown race.
