scipy: [set up dev environment] unable to run runtests.py

Hello!

I’m a first-time contributor and attempting to set up a dev environment by following the instructions here: https://docs.scipy.org/doc/scipy/reference/dev/contributor/quickstart_ubuntu.html#quickstart-ubuntu

on step 19, I’m trying to run the runtests.py file but I am getting the following: scipy/linalg/tests/test_decomp.py::TestEigh::test_eigh_integer realloc(): invalid next size Fatal Python error: Aborted at 21% completed.

I’m sure this is not an actual bug, so apologies if this isn’t the right place to post this, but I really want to contribute to SciPy and I haven’t managed to find any sort of fix to this from googling. I also recently installed Ubuntu to go through this set up so there may be some sort of issue there.
