Segfault after many stackframes

[Ole Tange]

This recursive function causes bash to segfault:

$ re() { t=$((t+1)); if [[ $t -gt 8000000 ]]; then echo foo; return;
fi; re; }; re
Segmentation fault (core dumped)

Ideally Bash ought to run out of memory before this fails. But an
acceptable solution could also be to say 'stack overflow'.
