Another stack overflow bug that we will not attempt to fix. It's a huge number of nested VSG elements. Better to crash than try to process content like this.

This seems to have been an instance of  crbug.com/718386  which was a real regression. I am not sure why the regression range was reported as the beginning of time though.
