Hi,
I found bash segfaults when running into an infinite recursion (details
below). I would expect it to either stop (or possibly exit) with a clear
error message instead. Here are the details (as given by bashbug). The
problem also happens with the latest bash version (5.2.0(1)-beta).
Yes. If you recurse indefinitely, you will eventually exceed your stack
size resource limit and get the prescribed fatal signal.
Description:
Infinite recursion causes bash to segfault.
The problem happens in interactive mode as well as in scripts.
Repeat-By:
~$ bash
~$ foo () { foo; }; foo
Segmentation fault (core dumped)
~$
If you are worried about this, set the FUNCNEST shell variable to an
appropriate value.
