i was going through the new features list in NEWS to see what cool things are 
in here and i saw the new checkjobs option.  is it just me or does this cause 
a non-login bash to crash at exit which leads to an infinite loop / cpu 
churning ?

$ gdb bash
(gdb) r
address@hidden 0:0 bash-4.0 $ shopt -s checkjobs
address@hidden 0:0 bash-4.0 $ exit

Program received signal SIGSEGV, Segmentation fault.
0x000000000047159b in exit_or_logout (list=0x0) at ./exit.def:116
116             else if (check_jobs_at_exit && stopmsg == 0 && RUNNING (i))

(gdb) bt

if i do run a job first like 'sleep 60 &', then it doesnt crash, but it does 
just exit right away ... or if i do `gdb --args bash -l`, then it works as 
expected.
