This is a common problem.  I am not intimately familiar with AAs, but it may have something to do with the fact that it's not a templated type.  That means the runtime is responsible for allocating AA nodes.

I think at the moment there is no way to do this.  I also think there is likely a bug report to this effect, and that others may have implemented better AAs to fix the issue.  Try searching the bug database for AA and NO_SCAN.
