It's a pointer arithmetics overflow problem: https://github.com/storpipfugl/pykdtree/blob/master/pykdtree/_kdtree_core.c#L1410 I'll look into giving pykdtree an overhaul to support contemporary data set sizes

Hi, Please specify OS and pykdtree version. Is this a problem for a specific dataset or a more general issue dealing with high dimension data? Does the error happen during...

The problem can be reproduced for tree construction on small datasets with high dimension (dims above 75 or so). Probably related to #38

The intention is to be drop-in compatible with SciPy's CKDTree so this is a bug

@djhoese you are invited as a collaborator now. @bjlittle what are the biggest problems with pykdtree in its current state?

It wasn't something I had considered. Would it make an important difference to some known use cases or is it more nice to have compatibility? Looking at the scipy code...

pykdtree has been validated against scipy.spatial.KDTree so disagreement of results is unexpected. @zyxue : Is it possible for you to provide a minimal data set that reproduces the problem?
