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.
Look for FUNCNEST variable. In recent release it is available.
