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 (7003c6f).

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.

Hi, just wanted to check if there was any update on this?

Hi @muhrin,

your error is very strange and we are not able to reproduce it on any of our computers (running either macOS and Linux).

It is probably due to an erroneous Cython code generationm, or to an erroneous compilation of the C code generated. Since we changed the Cython code a bit in the last weeks you could check whether the problem is still there now, and perhaps it would be best to try to install the package in a new Python environment first. If the problem is still there, it could be useful to check which compiler you are using.

Please give us further information if you are not able to fix this!
