self referencing flow type causing infinite loop

While using react-styleguidist, I noticed that I was getting this warning:

Warning: Cannot parse src/components/Button/Button.js: RangeError: Maximum call stack size exceeded

It usually means that react-docgen does not understand your source code, try to file an issue here:

While trying to debug this problem. I was having issues determining where the issue came from. I am using Flow to type my components out and Flow wasn’t reporting an error. However, I learned that the issue was coming from the fact that I had a type that defined a method that had a parameter that was the parent typing. While this works fine in Flow, it appears to cause issues when running through react-docgen.

Here is a slimmed down representation of the problem: Try Flow

Note: You may need to swap the engine to v0.64.0 or master as v0.65.0 is currently broken

Thanks for reporting this. I was easily able to reproduce and fixed the issue in #251 and #252.

Will release a new version soon.
