Description Raghavendra kamath 2015-06-04 12:09:16 UTC

When we use gradient tool ( radial or linear - i didn't try with all) after approximately 10th or near 20th time the software crashes (segfaults) without bug report wizard or any thing.



Reproducible: Always

Steps to Reproduce:
1.Open an A4 blank document in krita
2.choose gradient tool and pick any color and set it to radial or linear in tool options
3. Apply or draw gradient for over 10 times ( keep going till 20 -25 times, don't know exactly after which it crashes but definitely above 10 times )

Actual Results:  
after certain times krita crashes

Expected Results:  
crash shouldn't occur

here is the back trace --

Comment 1 Raghavendra kamath 2015-06-04 15:00:48 UTC

On additional testing I found that the crash happens when the undo stack size grows bigger than the swap undo memory limit set by the user in performance tab.

to reproduce the crash I had to set the swap undo limit to 100 mb so that it uses 100 mb and after that it starts swapping. But after reaching 100mb it crashes.
