I can confirm that the crash is still present in Emacs 24:
[larsi@stories ~/src/emacs/trunk]$ gdb --args ./src/emacs -Q --eval "(let (v)
(while t (setq v (cons v v))))"
[...]
(gdb) run
Starting program: /home/larsi/src/emacs/trunk/src/emacs -Q --eval \(let\ \(v\)\
\(while\ t\ \(setq\ v\ \(cons\ v\ v\)\)\)\)
[Thread debugging using libthread_db enabled]
