Let's look at one thing at a time.

The first two crashes should, I think, be addressed by this patch.
Could you try it?

Some of the later crashes are caused by this:

(gdb) set $a = x.Print
(gdb) p $a
$7 = <error reading variable>

I have a whole lot of patches related to member functions, that I
haven't had time to merge yet - and I would not like to look at this
until I've done that.
