bash has a special variable FUNCNEST to limit the recursion if you want to
prevent infinite recursion.
However, this subject has been discussed multiple times, it's easy to write
arbitrary code that crashes bash (not to mention the whole machine).
This doesn't necessarily mean that there is a bug in bash, but in your code.
If you can run arbitrary code in a shell (or even if your script doesn't
validate its input), your security is already compromised.
