<div dir="ltr">Hi Nathan,<div><br></div><div>I'm having a hard time getting a traceback that goes into the QuadTree source. The seg fault I get stops at QuadTree.so. Is there a way to recompile this in debug mode to get some more information? It doesn't look like pdb is able to step into QuadTree either.</div>

<div dir="ltr">Hi all,<div><br></div><div>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.</div>
