Actually, this bug has nothing to do with AA's. The problem is that double's
typeinfo.equals and typeinfo.compare does not respect NaNs:

import std.stdio: writeln;
void main() {
    double x = double.nan, y = double.nan;
    writeln(x == y); // prints false (OK)
    writeln(typeid(double).equals(&x, &y)); // prints true (WRONG)
    writeln(typeid(double).compare(&x, &y)); // prints 0 (WRONG)
}
