>From looking at the code changes, it does not fix casts from a derived class
array to a base class array.  However, that issue is captured in bug 2095.  I
don't think this means 2095 is not an important bug to fix, but it might be
that this bug is *really* simple to fix, and 2095 is not (Walter would know
better).  I'd rather have this part of it fixed than neither part fixed.

In any case, the example in comment 1 and the original description should
theoretically be fixed by the change, so we can at least close *this* bug.  I
agree that something needs to be done about casting a derived class array to a
base class array, and it seems like the solution proposed in the thread would
work.
