Follow-up Comment #4, bug #49729 (project octave):
I got a little closer now. The reason is X11 forwarding. Apparently, older
versions such as octave-3.8 do not crash when the X-channel is closed. Newer
versions (>= 4.0) do:
%> ssh -X some.host
%some.host> nohup octave --no-gui foo.m &
%some.host> logout
%> ssh -X some.host
%some.host> tail -1 nohup.out
%some.host> panic: Segmentation fault -- stopping myself...
Note that the logout hangs and has to be interrupted with "^C". By using "-x"
instead nothing hangs and no segfault occurs.
Why does the newer octave depend on the X11 channel, and is it intended?
