[Octave-bug-tracker] [bug #36866] Calling imagesc on complex matrix causes octave to crash

[Jordi Gutiérrez Hermoso]

Follow-up Comment #6, bug #36866 (project octave):

Never mind, I found the UB, and why it wasn't showing up in my development
build. There was an out of bounds indexing problem concerning empty matrices,
and in my dev build I build with bound-checking.

Rik, I have instead opted to warn and show the real part like imshow does. In
addition, I've added a few more checks on the C++ side to hopefully make it
impossible to crash Octave with a bad __go_image__ call:
