Hi all,

I'm trying to make projections of a rather large Enzo dataset and getting a segfault somewhere in Quadtree.so.  This dataset is ~230 GB in size with 27 levels of AMR.  As far as I can tell, the only hard coded limit I could find in QuadTree.pyx is for 80 levels, which I am clearly below.  Does anyone familiar with this part of the code have any idea if there are any other hard-coded limits in here that I might be exceeding?  If not, does anyone have any advice for how I might debug this?  I'm seeing this behavior in both yt-2.x and yt-3.0, so it does seem to be something intrinsic to the quadtree code.
