The `__cxa_atexit` interceptor is disabled for `SANITIZER_AIX` because Clang on AIX neither uses `__cxa_atexit` nor links against a library with such. This interceptor calls `StopInitOrderChecking()`, which is needed to prevent false positives for the `initialization-order-fiasco` error observed in the asan test `init-order-atexit.cpp` that uses the `strict_init_order` flag. For now, we'll disable the `strict_init_order` flag, but we'll look to support it in the future by implementing an `exit` interceptor or some other alternative. With the flag disabled, we won't update `init-order-atexit.cpp` to ensure it continues to pass and the false positive doesn't show up.
