That's a different feature. That allows ASan to be partially initialized and then the rest of the initialization is delayed until later. I believe this exists for Android.

The test case shows how to trigger the crash today (see `not --crash ...` line). The context here is we are looking for a way to make it possible to `dlopen()` the ASan library from a non-asanified process so that specific functions inside it can be called. Today this isn't possible.
