malloc() crash when running notebook_on_intrinsicdim_densityest_clustering

[muhrin]

I'm getting the following failure which crashes the notebook kernel when running notebook_on_intrinsicdim_densityest_clustering:

malloc(): invalid next size (unsorted)

This was on the latest commit at the time of writing (7003c6f41e4b353b9bf9f6b17a119ca9cb1917bf).

The error occurs when the notebook is trying to run _data.compute_clustering_optimised(Z = 1.65, halo=False)

I presume the error lies somewhere in the C code. If you'd like a C traceback just let me know and I'll try and attach a debugger.
