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() {


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.
