Le lundi 08 novembre 2021 à 13:18 +0000, Leonardo Vainsencher a écrit : The following code causes 'Segmentation fault' when inv() is executed: %%% begin octave code %%% pkg load io w = exp(-1i*pi/3); P_6x6 = [ 1, -1, 1, 1, 1, -1; ... 1, -w, w^2, w^3, w^4, -w^5; ... 1, -w^2, w^4, w^6, w^8, -w^10; ... 1, -w^3, w^6, w^9, w^12, -w^15; ... 1, -w^4, w^8, w^12, w^16, -w^20; ... 1, -w^5, w^10, w^15, w^20, -w^25]; Pi_6x6 = inv(P_6x6); % causes segfault D_6x6 = det(P_6x6); % causes segfault %%% end octave code %%% Octave run command (bash): octave-cli --no-init-file If `pkg load io` is omitted, no segfault occurs (io package is a dependency of communications). If pinv() is used instead of inv(), segfault does not occur either. Thanks for your bug report. I am unable to replicate your problem. This code works fine for me (tested on both Debian stable and unstable). Can you provide a full backtrace of the segfault? For instructions, see: https://wiki.debian.org/HowToGetABacktrace Can you also report the output of the following command: octave --eval "version -blas" Best, -- ⢀⣴⠾⠻⢶⣦⠀ Sébastien Villemot ⣾⠁⢠⠒⠀⣿⡁ Debian Developer ⢿⡄⠘⠷⠚⠋⠀ https://sebastien.villemot.name ⠈⠳⣄⠀⠀⠀⠀ https://www.debian.org
