Hi folks,
a suggestion about recursive function calls (and not only that, of course).
Do you see a way for Bash to pull the emergency break before it runs out
of stack here (to provide an error to the user, rather than a crash):
--------------------
f1() {
f1
}
f1
--------------------
Currently it runs into a SEGV, where the number of recurions depends on
the stack limit.
On a fast search I found no portable way, but there are ways for
specific platforms, like getrusage() when stack is reported there.
