segfault on stack blowup with ridiculous && chains

[Sarah Brofeldt]

I'm not sure whether this is actually acceptable behaviour, but a 
ridiculously long && chain blows up bash:

echo -n "" &&
echo -n "" &&
(... repeated 100.000 times)
echo -n ""
causes a segfault with ulimit -s 8192 in bash 4.3.42(1)-release and 
4.4.0(1)-rc2
