There must be something odd about your compilation if GDB can't see that
Lisp_TYPE is an enum.  Even before execution has started you should be able
to do:

    (gdb) p (enum Lisp_Type) 3
    $1 = Lisp_String

and at load_pixmap,

    (gdb) p name
    $1 = 60552283

    (gdb) xtype

should give:

    Lisp_String
    (gdb)

Even after you compiled it with -O0?

That's odd too and is presumably caused by the commands after "tbreak
init_sys_modes" in .gdbinit.  I can only suggest you rerun configure with as
few options as possible and do "make bootstrap".

I don't know what -dead_strip does but I'd start with simple things first.

I don't think it would help (more later).

That doesn't tell me anything about your version of GDB (above does though).
Apple have their own version of GDB and, while I would welcome you testing it
by running GDB in Emacs, it is probably easier to run it from the command line
to debug Emacs.  That way you only have to analyse one bug at a time.
