[Bug 1849460] Re: Segfault on dot(v,v')
This issue doesn't exist on 18.04 LTS and hence I've downgraded.

[Bug 1849460] [NEW] Segfault on dot(v,v')
Public bug reported: Octave was installed with apt-get install octave on a normal x64 machine running Ubuntu 19.04 disco No funny stuff. And all Recommended and Suggested packages were installed I get a segfault on the simple input: v = [3+4i 6+8i] dot(v,v') This is in GUI, CLI, octave-cli and running with sudo. Crashes in all cases with: fatal: caught signal Segmentation fault -- stopping myself... Segmentation fault PS: I've also separately test the Octave Snap package and it doesn't have this issue (but it doesn't run correctly with Emacs/Orgmode so it's not useful for me) ** Affects: octave (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849460 Title: Segfault on dot(v,v') To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1849460/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
