Right... probably nearly every language has a poor call stack overflow recovery story, not only because of non-heap stacks but I don’t think it’s relatively straightforward to get the program back into a well defined state after call stack overflow. Those errors can happen on any line of code so unless every line of code is guaranteed to be atomic and a coherent state can be derived from the intermediate states, the program will be in an undefined state.
