I think this actually takes a Lisp expression, such as a symbol (eg,
"codepoint" from the backtrace produced by "lbt").
To print a Lisp_Object whose C address you know as a C struct, use
"pobj". I think you don't need the cast. So
(gdb) pobj 140737322320744
Thanks. Here's the result of a few such calls that with any luck are
the relevant ones.
