Package: octave
Version: 6.2.0-1
Severity: important
X-Debbugs-Cc: none
Dear Maintainer,
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.
Here is the output of `pkg list`:
