That is the normal expected behaviour.

What do you expect this should do:
$ foo() { foo ; } ; foo

This code instructs the function foo to call itself again
and again without limit forever.

So it tries to do that until the process entirely fills its call
stack with return addresses and runs out of memory
resources at which point the operating system will kill
the process.

That's not bash' fault. That's the programmers fault.
