Address space of struct member

I'm still not back.  I hopefully will be around next week sometime.

The expr_to_var_sym() function, is returning the wrong symbol for you.  If
you pass it foo->bar->baz then the symbol it returns is for "foo".  There
isn't really a symbol for ->baz because that's not a variable by itself.
If you try expr to var sym() on foo[bar] then it fails because there are
two symbols.

But you should be able to use get_type() to look up the information you
want.

The symbol hook is not really useful for you in this situation either.w
