Ah, this appears to be closely related to lmcinnes/umap#99. (Didn't think to check the UMAP issues before, but found a reference in the tests.) The check for abs(margin) < EPS looks like it was added in response to that issue. My example is a set of nonidentical data points that nevertheless sneaks by this check.
My proposal is to check for trivial splits and do a random assignment in that case, and also add a depth limit for trees as a failsafe. I'll submit a PR shortly.
