390 is not an Emacs integer; it has type Lisp_Cons.
It's a bogus Lisp_Cons value, but it's encoded as a
Lisp_Cons.

c is 0xD81000, which is also bogus (it's not a valid
character value), and this may explain why val is bogus.

The fact that the string indexes are out of range could
explain why c is bogus.
