You may not delete aa elements within a foreach loop. The foreach 
iterator will be confused.

There are other ways. For instance:

foreach(key;aa.keys)
	aa.remove(key);

or faster (as you seem to want to delete all elements), but ugly, 
hackish and undocumented:

struct BB { void *[] buckets; size_t nodes; }

...

(cast(BB*)&aa).buckets = null;
(cast(BB*)&aa).nodes = 0;

(A wish would be for the above to be implemented as aa.clear())

Or if you just want to forget about your current aa instance:

aa = null;
