I tried to reduce this down as much as possible -- produces a crash ("We're sorry for the inconvienience..." etc).  Commenting out the constructor and destructor will produce an "cpp 5484" ICE instead of a crash.  These bugs also happen in the 8.49 version.

Thanks for looking at this -- Les Baker


--- begin code ---
template <typename T>
class A {
        template <typename T> class A_inner;

        // Comment out the two lines below to produce ICE
        A() {}
        ~A() {}

        void method(const T);
};

template <typename T>
class A<T>::A_inner
{
};

template A<int>::method(const T);
--- end code ---

Thanks for reporting this.
