[SOLVED] matplotlib.pyplot show() function triggering coredump crash

Hi,

  From yesterday update (and retry an update this morning) it became impossible to show my plots from matplotlib.pyplot. It always crashes while trying to show the windows whatever the backend (default Qt6 for me, GTK3Agg, ...) I choose.

  After investigating with gdb, I found out that the culprit was cblas.so.3 which on my current install rely on openblas.

  The solution I found was to downgrade blas-openblas and openblas. Here is the commands I used.

cd /var/cache/pacman/pkg/
pacman -U blas-openblas-0.3.26-1-x86_64.pkg.tar.zst blas64-openblas-0.3.26-1-x86_64.pkg.tar.zst openblas-0.3.26-1-x86_64.pkg.tar.zst openblas64-0.3.26-1-x86_64.pkg.tar.zst

  For those who might encounter the same issue, I hope it will help,
