bash crashes with infinitive recursion

[Stepan Koltsov]

Binary package hint: bash

Steps to reproduce:

===
# cat crash.sh
f() {
    if true; then
        f xx
    fi
}

f xx

# bash crash.sh
segmentation fault bash crash.sh

# bash --version
GNU bash, version 3.2.13(1)-release (i486-pc-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.

===

Expected behaviour: message "stack overflow in crash.sh" printed to stderr, nonzero exit code.

Appears to have been fixed in bash 4.2.25
