Segmentation fault for circular definition in words

[HyeonseopJeong]

Hi ,
I found that call stack overflow occurs when use a word defined circularly.

A word can define circularly like below.

a "a"

or It can be defined circularly with multiple words like below.

a "b"
b "c"
c "d"
d "a"

And program is terminated by segmentation fault when there is the word defined circularly in the expression.

$ clac "a"
Segmentation fault

@HyeonseopJeong Thanks a lot for the report! I've been thinking about it and I think there isn't a good way to solve it in code. Maybe the best we can do is to clarify in the documentation that circular references will cause a segmentation fault. Let me know if you have other ideas.

@soveran Thanks for the comment!
I also think it is difficult to solve neatly in code.

I think that's a good idea to clarify it in the documentation.!
