Hi JJ585,
Thanks for the bug report.
I just ran your reproducible example, but I don't get an error. See printout below. Also using R 4.4.1 with scclust 0.2.5.
Could you provide more details on how the bug arises?

The error occurs when hierarchical_clustering function is called (Shit+Enter) - it starts execution for a short period of time and then the window appears that states that session has been terminated. I tried to step into the function and call it line by line and the error occurs at
clustering <- .Call(Rscc_hierarchical_clustering, distances, size_constraint, batch_assign, existing_clustering)
Ok. I can still not reproduce the bug, which makes it difficult to bug hunt.
I'm using MacOS, so this might be something that doesn't pop up on that platform. I will try to reproduce on other platforms, but it will take a bit longer to do. Stay tuned.
Thanks again for the careful bug report. I very much appreciate it.

I added screenshot mp4 to show how the error happens.
The error occurs at external .Call()
Thanks!
To clarify, I wasn't doubting whether you had the bug. But I need to reproduce it in order to start investigating where it comes from.
I have a problem with running _hierarchicalclustering() function both on R Windows and Linux RStudio server, in both cases this function crashes my R session when I use _existingclustering parameter.
I tried to debug this function, but the problem is at the C level under .Call(Rscc_hierarchical_clustering), probably some segmentation fault.
Reproducible example here.
My setup: Red Hat Enterprise Linux release 9.4 (Plow) or Windows 10 R 4.4.1 or RStudio server 2024.09.0 Build 375 with R 4.4.1 scclust version 0.2.5
