Hi Gergely! > I stumbled upon a recursion overflow crash in BASH.
There are many ways to exhaust memory (and other) recources, recursion is one them. In your case a variable like SRCNEST (and all the code with its performance impacts needed behind it) might help, but what exactly is the advantage of a "maximum source nesting level exceeded" error over a segmentation fault? Next we will need MAXARRUSAGE, MAXBRACEEXPAN, ... > There's a slim chance this might be exploitable. I would really be interested in an example. Best regards, Martin
