[Octave-bug-tracker] [bug #39925] imagesc crash

[Mike Miller]

Update of bug #39925 (project octave):

              Item Group:                   Crash => Regression             

    _______________________________________________________

Follow-up Comment #4:

Marking as regression.

It doesn't matter whether image or imagesc is called. It has to do with the
x-axis limits as they are specified. This works:


octave:1> img = rand (2, 2);
octave:2> graphics_toolkit ("fltk");
octave:3> image ([1e9 2e9], [1 2], img);
octave:4> image ([1e10 2e10], [1 2], img);


but this crashes:


octave:5> image ([1e9 1e9], [1 2], img);
octave:6> image ([1e10 1e10], [1 2], img);


And here is a backtrace:
