[Octave-bug-tracker] [bug #41699] image package: imrotate causes a segmentation fault when exiting Octave

[Ian Journeaux]

Follow-up Comment #7, bug #41699 (project octave):

After some more testing, it appears that the problem is not related to the
version of the image package.

To eliminate memory as a possible issue, I reduced the size of the array

AI3c1=imread('AI3c70.tif');
AI3c = AI3c1(1:5,1:5)
AI3cr=imrotate(AI3c,5,'nearest','crop');

This still generates the error so I further simplified the test program to
just the 5x5 array read in from the image

AI3c1 = [88,  113,  120,  126,  132;
  113,  142,  151,  161,  170;
  120,  151,  161,  170,  179;
  126,  161,  170,  179,  189;
  132,  170,  179,  189,  198;]
AI3cr=imrotate(AI3c1,5,'nearest','crop');

This works. Then tried

AI3c2=imread('AI3c70.tif');
% AI3c2 is unused.
AI3c1 = [88,  113,  120,  126,  132;
  113,  142,  151,  161,  170;
  120,  151,  161,  170,  179;
  126,  161,  170,  179,  189;
  132,  170,  179,  189,  198;]
AI3cr=imrotate(AI3c1,5,'nearest','crop');

This results in the segmentation violation on exiting Octave.
It would appear that the problem is associated with imread.
