New comment by tornaria on void-packages repository https://github.com/void-linux/void-packages/pull/46553#issuecomment-1755231377 Comment: Alternatively, we could try updating to 3.0.3 + https://github.com/cython/cython/pull/5752 which claims to fix the scipy build regression. I haven't tested that one though. Edit: or just wait for 3.0.4. This only affects sagemath with cython 3 which is not what we ship. I already have patched cython in my development box. As long as this is fixed by the time sagemath 10.2 is released (cython 3 only), we'll be fine.
