I don't actually know what octave does,
octave segfaults ;-). Stephen asked me to try qt5-core-5.10.1_2 as I had qt5-core-5.10.1_1 installed. So, the sequence went as follows. % su % pkg delete octave (removes all things octave) % cd /usr/ports % svn update % make fetchindex % svn revert -R math/octave (Remove my reverting qt4 to qt5 change) % portmaster math/octave (this installed qt5-core-5.10.1_2) % portmaster math/octave-forge-netcdf % portmaster math/octave-forge-signal % exit (leave su to root) % octave --gui (lauched octave and watch it die) % gdb81 $PATH_TO/octave-gui octave-gui.core warning: Unexpected size of section `.reg-xstate/100615' in core file.
