Ah. That's right. Try the same thing with "print"
instead of "ldp".
Probably it should have been "print" in the first place.
Not much better:
(gdb) print (Lisp_Object) 39408616
$2 = 39408616
(gdb) print * (Lisp_Object *) 0x7ffff8aec010
Cannot access memory at address 0x7ffff8aec010
(gdb)

Well, you could always run xemacs under gdb. For me there is no
noticable performance impact, but I often get much better stack
traces, and ldp (eval and print a Lisp expression) and lbt (Lisp back
trace) work because the process is still live, just suspended.
OK, I'm doing that now. Of course now that I'm actually wanting it to
crash it won't :-)
Thanks,
